Abstract:

Formation damage  by gel particles has become one of the most important problems in mature reservoirs.  The objective of the quantitative analytical model is to identify an analytical model to the best fit of the preformed particle gels (PPGs)  filtration test results. This work will analyze the experiments results of low permeability core samples to evaluate the effect of various brine concentrations and particle sizes. This study used a linear analytical model relationship between cumulative volumes versus filtration time with a good fits result. Linear curve equations for the best fitting equation was obtained.  According to quantitative analytical model for all of our filtration tests, the cumulative filtration test volume is explained by the following equation: (Vcf = m t+ b ).  Where, Vcf is the cumulative filtration volume, m is the slop of the linear curve, t is the filtration time, and b is the intercept of the linear curve. Quantitative analytical model results showed the value of the slop m increases as the injection pressure increases. Compared with the experiments, the results show that, if the value of the intercept b > 2 the damage occurred because the gel particles invasion started into the core surface. Results from the quantitative analytical model were indicated to have a good fitting with almost all of the experimental results. It is the first time to use quantitative analytical model to analysis the formation damage by the PPGs. The results can be used to select the best gel treatment design.

Tohru Setoyama is a fellow and an executive officer of Mitsubishi Chemical Corporation (MCC). He has largely contributed to the several commercialized catalytic processes and to the launch of several businesses related to inorganic functional materials. He is regarded as one of the key persons to bridge between academia and industry in Japan. Now he is a project leader of ARPChem project supported by New Energy Development Organization (NEDO) and Program officer of "Hyper nano space Design" project supported by Japan Science and Technology Agency (JST). 

Abstract:

This project is composed of three scientific programs as follows.

Ø  Catalyst development for water splitting under sunlight to produce hydrogen.

Ø  Safety separation of hydrogen from hydrogen/oxygen mixture generated by water splitting.

Ø  Olefin production from CO₂ and solar hydrogen.

The goal of catalytic performance of water splitting under visible light is 10% as a sun light to hydrogen conversion (STH) and we have to establish a process having a sufficient scalability and a reasonable hydrogen production cost comparable to fossil-resource-based one.  Here we propose a photo-catalyst sheet, which will satisfy these requirements in the future.

MCC can contribute to the ARPChem project by extending its zeolite-related technologies.  For example, we are investigating in the project a safety hydrogen separation system from the mixture of H2 and O2, which is just in the middle of dangerous explosive zone. Molecular sieving by size recognition is very important to realize this technology.  Another example is the catalysts for MTO reaction.  SAPO-34 and ZSM-5 have been the only commercialized catalysts for MTO, while we are developing a new type of zeolite catalyst in the project. It has a remarkable durability even in a high temperature steam atmosphere. We would like to argue not only the outline of ARPChem project but also the strategy for chemical industry in order to realize the drastic reduction of CO2 emissions from the view point of diversification of chemical resources such as utilization of CH4, CO2, and solar hydrogen.

On the other hand, MCC has been developing other several technologies and processes related to synthesized zeolitic materials.  Representative examples of our activity are interconversion of olefins such as ETP (ethylene to propylene), BTP (propylene from methanol or higher olefins), adsorption heat pump (AHP, for desiccation and air conditioning by water vapor ad/de-sorption), zeolite membrane for gas separation, and SCR catalysts.  Zeolite membrane is also applicable to the chemical processes under equilibrium control such as methanol synthesis and hydrogenation of CO₂.  We have developed a sealing methodology, which enables good sealing performance under practical operation conditions such as a high pressure and temperature.

Elizabeth Carvalho Leite Cardoso completed her PhD last June 2014, in Nuclear and Energy Research Institute/Universidade de São Paulo (USP), Materials. Postdoctoral studies being currently developed in CQMA, involving PP/HMSPP foams with aliphatic polyesters intercalated with nanoclays and PLA/PBAT flexible films reinforcing with bio-calcium carbonate.

Abstract:

Polymers are used in various applications and in different industrial areas providing enormous quantities of wastes in environment. Among diverse components of residues in landfills are polymeric materials, including Polypropylene, which contribute with 20 to 30% of total volume of solid residues. As polymeric materials are immune to microbial degradation, they remain in soil and in landfills as a semi-permanent residue. Environmental concerning in litter reduction is being directed to renewable polymers development for manufacturing of polymeric foams. Foamed polymers are considered future materials, with a wide range of applications; high density structural foams are specially used in civil construction, in replacement of metals, woods and concrete with a final purpose of reducing materials costs. At present development, it was possible the incorporation of PP/HMSPP polymeric matrix blends with sugarcane bagasse, PHB and PLA, in structural foams production. Thermal degradation at 100, 120 and 160°C temperatures was not enough to induce biodegradability. Gamma irradiation degradation, at 50, 100, 150, 200 and 500 kGy showed effective for biodegradability induction. Irradiated bagasse blends suffered surface erosion, in favor of water uptake and consequently, a higher biodegradation in bulk structure.

Abstract:

Due to constant increase in the demand for highly saturated Group II and Group III base oils and their application in use as special lubricants, it is a must to have a clear picture of structural distribution of base oils. In this study, pressure differential scanning calorimetry (PDSC), rotary pressure vessel oxidation test (RPVOT), kinematic viscosity (KV), Noack volatility and elemental analysis as physico-chemical tests are studied for Group II base oils. The inferences derived from these analyses established the relationship between the chemical structure and selection of the base oils to meet future product specifications. 1H and 13C NMR (Nuclear Magnetic Resonance) data had also been used to generate average structural profile and it was used to account for the oxidation stability of the selected base oils.

Abstract:

This research focused to prepare the natural zeolite based catalysts for hydrocracking and to compare their catalytic reactivity. The clinoptilolite type natural zeolite of Tsagaantsav in Dornogobi province and the paraffinic atmospheric residue of Tamsagbulag crude oil in Dornod province were used in this research. The quality of adsorption or the ion exchange capacity of natural zeolite was improved from 0.21mmol/g to 0.41 mmol/g after washing and thermal activation of natural zeolite. The Ni or Fe ion was loaded into the zeolite sample which was enriched and calcined previously, by ion exchange method. The prepared Ni/zeolite, Fe/zeolite catalysts were identified the clinoptilolite type zeolite by database in D500 instrument, which was used in X-ray diffraction analysis. It means the structure of natural zeolite was not broken down during the metal loading. The researchers assigned that the thermal stability of Tsagaantsav zeolite is 950^oC of temperature. Therefore Ni/zeolite, Fe/zeolite catalysts were possible to use in hydrocracking process, which is carried out at 450^оС - 500^оС of temperature. The atmospheric residue (AR) conversion, the contents of sulfur were determined after hydrocracking used the prepared zeolite catalyst, the commercial catalyst and without catalyst. The AR conversion in hydrocracking, in with prepared zeolite was used, was 22.5% higher than none catalytic process and 8.9% higher than commercial catalyst. It is proved that both of modified zeolite catalysts worked effectively as a catalyst in hydrocracking of AR. Even so the contents of sulfur in middle and heavy fraction were 490-615 ppm after hydrocracking with Ni/zeolite, Fe/zeolite catalysts. This result was evidenced the Ni/zeolite, Fe/zeolite catalysts were inactive at hydrodesulfurization, because the contents of sulfur in middle and heavy fraction were 370-478 ppm after hydrocracking without catalyst. Therefore need the sulfur removal process for products after hydrocracking with Ni/zeolite or Fe/zeolite catalysts.

Abstract:

Studies of thermal transformations of naphthalene, octafluoronaphthalene and their binary mixtures under pressure of 8 GPa have been undertaken as models for gaining understanding of processes of carbonization, graphitization and diamond formation in pure hydrocarbon, fluorocarbon and carbon-hydrogen-fluorine-containing systems under high pressures. The studies found a significant reduction in the initiation temperature thresholds for all major thermal transformation processes in case of binary mixtures with respect to thresholds for pure naphthalene and fluoronaphthalene. The naphthalene-octafluoronaphthalene mixture was selected as an example for investigation of the nature of large scale formation of micro (5-20 μm) and nanosize (10-20 nm) fractions of diamond in the transformations of binary mixtures of hydrocarbon and fluorocarbon compounds under high pressures. The origin of nanodiamond was found to be due to the specifics of carbonization of fluorocarbon compounds under pressure, which at 800-1000 °Ð¡ produces, along with submicron particles of graphite-like material, a significant amount of closed shell 2-5 layer carbon nanoparticles of 5-15 nm size. These carbon nanoparticles act as precursors for formation of nanosize diamond fractions in the  transformations of binary mixtures of hydrocarbon and fluorocarbon compounds.  These results potentially open a new direction for metal catalyst-free synthesis of nano/micro-size fractions of pure and doped diamonds for broad areas of applications.

Abstract:

The paper gives a brief assessment of the existing methods of purification of flue gases from nitrogen oxides and carbon dioxide. To improve the environmental safety of the heat source is proposed to consider it not only as a source of heat, but also as a chemical reactor capable of producing chemical products. Given example of innovative technical solutions for the treatment and disposal of flue gases with the release of carbon dioxide as a commercial product (RF patent â„–2371238, 2009) and given an approximate economic calculation for the implementation of this decision for the boiler capacity of 20 tons of steam per hour, running on natural gas, the average consumption of flue gases V=20000 m³/h and an average initial concentration of NO_x=3·10^–4 % RPM and СО₂=10% RPM. With the average efficiency of flue gas treatment of NO_x and СО₂ equal 70%. Accordingly, if the time of the boiler in the year, Тset=8000 hours, the number of captured and recycled, Ðœ_NOx=40 tons/year, of carbon dioxide, Ðœ_СО2= 22400 tons/year. It is shown that at current prices for produced with help heat generator heat and commercial carbon dioxide economic effect of the carbon dioxide is 3.5 times higher than the effect of the realization heat and, thus, there is a real opportunity to improve the economic efficiency of the heat generator by increasing its ecological security in the use innovative technical solutions for flue gas cleaning.

Myungbae Kim has completed his PhD from Korea Advanced Institute of Science and Technology. He is the principal researcher of Korea Institue of Machinery & Materials and also the professor of Plant System and Machinery, Korea University of Science and Technology. His research interests include the spread of liquid pool and fire and explosion consequence analysis in the plant safety study.    

Abstract:

The study of liquid pool spreading plays an essential role in the quantitative risk assessment of accidentally released cryogenic liquids, such as LNG and liquefied hydrogen because the spreading of such liquids is the first step in the development of multi-staged accident sequences leading to a major disaster. There is a wide range of models used to describe the spreading of a cryogenic liquid pool. Many of these models require evaporation velocity, which has to be determined experimentally because the heat transfer process between the liquid pool and the surroundings is too complicated to be modeled. Measurement of the evaporation velocity had been conducted in the first place with a non-spreading pool that was formed by pouring of cryogenic liquid onto bounded ground instantaneously so that the discharge time was much smaller than the total evaporation time. Recently, the measurement methodology for a spreading pool was developed by the research team including the author. A constantly-released-flow onto unbounded ground was intended to generate the spreading pool because in almost all real accidents, a cryogenic liquid spills and spreads over a large or unbounded ground such that the pool spreading process should be taken into account. In case of the spreading pool, a greater release flow rate is found to result in a greater evaporation velocity, and the evaporation velocity decreases with the spreading time. Since the spreading pool in the author’s work receives heat more effectively from the ground as compared to the non-spreading pool, the measured evaporation velocities are much greater in the spreading pool than in the non-spreading pool.

Abstract:

The fine mineral solids in Alberta oil sands are associated with a significant amount of organic matter. These organically-modified solids hinder bitumen aeration and stabilize water-in-oil emulsions, leading to low bitumen recovery and poor bitumen quality. The study of these organic coating on the fine solids has been elusive due to the nanometer length scale and the unsuitability of sampling in high vacuum sample chambers. In the present work, we report the first application of PeakForce Quantitative Nanomechanical Mapping (QNM) Atomic Force Microscopy (AFM) to study the organic coating on the fine solids extracted from bitumen froth. Taking advantage of the simultaneous nano-scale resolution topographic imaging and adhesion mapping enabled by the PeakForce QNM-AFM, the mineral and organic components in the fine solids were distinguished due to their variations in shapes and mechanical properties. The organic coating on the clay minerals was clearly visualized on the adhesion maps, showing a patchy-distributed structure. The area percentage of the surface organic coverage on clay basal faces was calculated to be 17±6%, and the average thickness of the organic coating was estimated to be 1.4 nm based on the adhesion maps. The organic matter coated on bitumen froth fine solids, which cannot be washed off by toluene, was softer than the asphaltene fraction of oil sands bitumen.

Abstract:

Aromatics and cyclic-hydrocarbons are the significant components of jet fuel with high energy-density. However, conventional technologies on bio-fuel production can’t produce these products without further aromatization and isomerization. In this work, renewable liquid fuel with high content of aromatics and cyclic-hydrocarbons was obtained by aqueous catalytic conversion of biomass sorbitol over Ni-HZSM-5/SBA-15 catalyst. Texture characteristics of the catalyst were determined by physisorption of N₂, which indicated its bimodal pore structures with microporous (HZSM-5, pore width: 0.56nm) and mesoporous (SBA-15, pore width: 8 nm). The surface acidity included weak and strong acid sites, predominantly Lewis type, was further confirmed by the NH₃-TPD and Py-IR analysis. The catalytic performances were tested in a fixed-bed reactor under the conditions of 593 K, WHSV of 0.75 h^-1, GHSV of 2500 h^-1 and 4.0 MPa of hydrogen pressure. Whereby, oil yield of 40.4 wt% with aromatics and cyclic-hydrocarbons content of 80.0% was obtained.

Abstract:

The oxidative degradation products formed under both the prolonged storage and thermal stress are a problem in the utilization of Kerosene fuels. Researchers are directed in developing fuel stabilizers that are increasingly cost-effective, do not degrade the performance of fuel and are environmentally acceptable. Our interest in anilines extracted from Iraqi crude oil has led to evidence that they are excellent antioxidant stabilizers for tetraline at elevated temperatures. The results of stability experiments for thermal and oxidative degradation of two crude Kerosene fuel samples obtained from al-Dora refinery with 0.20% sulfur contents (sample A), and from Kirkuk refinery with 0.25% sulfur contents (sample B) were evaluated in these stability tests in comparison with other well-known stabilizers. The samples were treated as follows:

1. They subjected to long period of storage (90 days) without any additives.

2. They exposed to thermal aging at elevated temperature (393K) without any additives for 3 hours. Chemical factors preventing formation of color, insoluble sediments and gums were studied by modeling generally accepted degradation mechanisms.

In this paper we will report our mechanistic investigation into the chemical details of the stabilization and effect of chemical structure of extracted N,N-P-methyl phenyl acetone (MPA) and N, N- phenyl acetone (PA)on the activity of deposits formation in kerosene in a comparison with 2, 6-di-t-butyl-4- methyl phenol (Unol), and tertiary alkyl primary aniline(TAPA) with 9, and 12 carbon atoms.

Ryo Takahashi is Graduate School of Hirosaki University. He study combustion phenomena of liquid fuel in partial gravity environment  at Ito laboratory.

Abstract:

There are few combustion experiment reports of partial gravity environment such as Mars and Moon. The flame characteristics of pool fires such as their height vary depending on gravity. To improve our understanding of the effects of gravity on flame characteristics, we experimentally investigated small-scale pool fires under conditions of normal to partial gravity; using the drop tower at Hirosaki University in Japan to obtain arbitrary partial gravity conditions, which varied from 1G to 0.55G. We performed the measurement of the temperature distribution with a fine thermocouple and that of the flame height with a digital camera. To clarify the effect of gravity on the heat feedback of pool fire, we estimated the convective and radiative heat feedback amount to the fuel surface based on the temperature distribution. From these analyses, we made clear that the heat feedback amount of pool fires decreases under partial gravity environment. We also discussed the effect of gravity on the liquid phase of fuel based on results.

F R Sultanov is a PhD-student of Al-Farabi Kazakh National University and Junior Researcher at the Institute of Combustion Problems (Republic of Kazakhstan, Almaty). His scientific interests are processing of heavy oils, oil sands and synthesis of carbon nanomaterials, 3D structures and applications in oil and gas sector.

Abstract:

Statement of the Problem: The explosion of BP’s Deepwater Horizon oil rig released 210 million gallons of oil into the Gulf of Mexico. Oil booms, combustion, and oil skimmer vessels were used to clean up the oil spill, but often with poor efficiency and even with undesirable environmental side effects. There is a clear need of new cleanup materials for the collection and separation of large amount of organic pollutants from water surfaces. As a major oil production country, Kazakhstan is at risk of major disasters like spill at Caspian shelf, or during the processing and transportation of oil products. The purpose of this study is to obtain and study the possibility of using spongy carbon nanomaterials (CNMs) based aerogels and sponges for elimination of oil spills.  

Methodology & Theoretical Orientation: Composite aerogels were obtained using highly uniform graphene nano-platelets with thickness of 2 atomic layers comparing to ≥4 layers by the top-down process by microwave-enhanced chemical vapor deposition (MECVD) process (bottom up approach), multi-walled carbon nanotubes (MWCNTs) and chitosan as a binder. Hydrophobic and oleophilic sponges the walls of which are coated with graphene oxide and MWCNTs were obtained by “dip-coating” method.

Findings: The sorption capacity of composite aerogels based MECVD graphene/ MWCNT/ chitosan (1 g) in regard to diesel is 101.3 g. It was found that these materials are good water repellent reusable sorbents for organic liquids. Sponges are highly hydrophobic due to existence of CNMs on their surface, their sorption time is fast and they can be easily regenerated by squeezing and heating.

Conclusion & Significance: The possibility of use these CNM’s coated sponges as a Super-hydrophobic and super-oleophilic filters on combined vacuum-oleophilic installation for collection of organic liquids from the surface of water is studied.

Abstract:

Natural bitumen in tar sands deposits represents a very rich source of energy potentially. At the same time accessible to the main part of those stocks is difficult, and for the conversion of low-sulfur liquid bitumen products you require non-standard solutions, since the properties of conventional oil and bitumen are significantly different. To extract the bitumen must first carry out hydraulic fracturing, and only after that you can use thermal production methods. Currently, commercial production of bitumen in Canada is carried out using mining methods. The objective of the study was to collect a sample of the tar sand Beke field (Kazakhstan), extract of sand and extracted asphaltenes from organic part, as well as products of their transformations during thermal processing. The molecular weight of tars and asphaltenes of natural bitumen and their cracking products measured by cryoscopic in naphthalene created in Institute of Petroleum Chemistry on Krion instrument. Elemental characteristics of samples were determined by elemental analyzer Vario MICRO cube (Germany). Monte Carlo method was used to construct the molecular structure of macromolecular compounds. Constructing molecular structure program is written in Fortran Version 6.6. The developed program for the construction of molecular structure used as input parameters analytical data and calculated using the structural-group analysis. The input parameters are the analytical data obtained from elemental analysis, PMR spectroscopy, molecular weight of tars and asphaltenes. The calculations data determined the most stable conformation of tars and asphaltenes molecules. It was found that the stability of the molecules affect structural characteristics such as the number of structural blocks, their size and spatial arrangement of atoms with respect to each other. Consisting of more structural blocks of smaller size molecules are more thermodynamically stable as compared to mono block structure. Constituting molecules characterized as thermodynamically more stable than a non-layered structures.
