Abstract:
The recent development of commercial software enables determination or prediction of catalytic activity. This has led to commercialization and potential commercialization of the TMS catalytic materials as described in reference 1. Additionally, we have developed a fundamental understanding of the catalytic materials as described in reference 2. This report will describe how the following interdisciplinary scheme has been applied to the TMS catalytic materials:
Theory <---> Synthesis <---> Characterization <---> Application
Shell Oil after WWII commercialized unsupported TMS catalytic materials but these were soon replaced for commercial reasons with the currently popular Al203 supported catalysts. In the 1970’s researchers concluded, incorrectly, that the Al203 was fundamentally involved in the Promotion Effect. This effect today is understood in detail as the sharing of non-bonding d electrons in clusters that mimic noble metal for example Co9S8 + MoS2. This result we call Goldilocks, which will be discussed during the report.
The model described in reference 2 is a detailed realization of the Contact Synergy described in reference 1. MoS2 interfaces with Co9S8 with a lattice fit at 1 1 1 crystal face. This creates at the interfaces a cubic lattice with the appropriate Co/Mo electron transfer allowing observed promotion. We will now discuss in detail the structure and meaning of Contact Synergy. Several papers are in preparation on this subject and will be discussed in detail.

Abstract:
Emergency oil spills during transportation of them by water way, from offshore oil drilling rigs and other sources can rapidly result in harm to the ecosystem and leads to negative and social impact. Oil, which falls on the water surface, prevents the penetration of sufficient sun lights and reduces the level of oxygen dissolved in water and it is make a great harm to the flora and fauna of water area. Therefore the development of effective methods on oil spill elimination is a task of singular importance. It is now one of the most common methods of oil spill on the surface is burning. Burning can be used where other methods are not effective spill response, and can be done in parallel with other methods of spill after determining an appropriate method for a particular site or geographic region. In the paper provides an overview of the current state of the problem, and research results on combustion of Karazhanbas and Tengiz oil on water surface were carried out. It has been established that minimum thickness of oil blanket, allowing to initiate and support combustion process, lie in the range of 3 - 5 mm. For ignition and maintenance of stable combustion of oil on water surface, the synthetic sorbent was suggested. It is found that, the synthetic sorbent accelerates the combustion process of oil on water surface threefold in comparison with combustion process of oil without sorbent. It is shown that the remaining mass of oil on water surface after combustion process termination, presents the bitumen substance, having a good adherence and strong adhesion, that allows to take it with high efficiency by mechanical method.

Abstract:
Interaction between the polymer and surfactant has been extensively studied for its widespread applications in many industries. They play an outstanding role in pharmaceuticals, detergents, pesticides, cosmetics, and enhanced oil recovery. Specific interests on the polymer and ionic surfactant systems are because of its characteristic physicochemical properties at different possible combinations. The characteristic behaviour of polymer with surfactant is similar to surfactant micellization in solution and occurs above a critical aggregation concentration (cac) which is lower than the corresponding critical micelle concentration (cmc). It is well known that the hydrophobic character of both the polymer and surfactant is responsible for the interaction. The nature of these interactions has been investigated and reported by few researchers and reported that surfactants at high concentration can displace polymer from the air/water interface depending on the system. Limited work has been reported on interaction of Xanthan gum with CTAB and gemni surfactant (16-5-16) . Therefore present study describes the interaction between the cationic gemini (16-5-16) surfactant and their conventional counterpart with a polymer at different temperatures and to see the effect of hydrophobicity and the molecular interactions by using the surface tension measurements. The purpose of this study was to investigate the interaction between water soluble polymer (Xanthan gum) with cetyltrimethylaaminium bromide (CTAB), and gemini surfactant, bis (hexadecyldimethylammonium) pentane dibromide (16-5-16) at two temperatures 310.15 K and 318.15 K by using surface tension measurement . The behaviour of surfactant –polymer interaction was found to be dependent on both surfactant and polymer concentrations. After the critical aggregation concentration (cac), interaction between the water soluble polymer and surfactants was started and above the critical micelle concentration (cmc), normal micelle formation started and now polymer was saturated by surfactant with no further change of surface tension of the solution for particular concentrations of the polymer solution. It was found that the gemini surfactant interacts strongly with Xanthan gum as compared to conventional surfactant CTAB.

Abstract:
Due to constant increase in the demand for highly saturated Group II and Group III base oils and their application as special lubricants; it is a must to have a clear picture of structural distribution of base oils. In this study, pressure differential scanning calorimeter (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 has been used to generate average structural profile and it was used to account for the oxidation stability of the selected base oils.

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 as 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 160ºC temperatures was not enough to induce biodegradability. Gamma irradiation degradation, at 50, 100, 150, 200 and 500 kGy showed to be effective for biodegradability induction. Irradiated bagasse blends suffered surface erosion, in favor of water uptake and consequently, a higher biodegradation in bulk structure.

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 were 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 for analysis of the formation damage by the PPGs. The results can be used to select the best gel treatment design.

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 0.21 mmol/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 as clinoptilolite type zeolite from the 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 at 950ºC temperature. Therefore Ni/zeolite, Fe/zeolite catalysts were possible to use in hydrocracking process, which is carried out at 450ºÐ¡-500ºÐ¡ 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 with the prepared zeolite 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 the contents of sulfur in middle and heavy fraction were 490-615 ppm after hydrocracking with Ni/zeolite, Fe/zeolite catalysts. This result was evident that 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, this is needed for the sulfur removal process of products after hydrocracking with Ni/zeolite or Fe/zeolite catalysts.

Title: Aerogels and sponges based on carbon nanomaterials for oil/water separation
Time : 16:00 - 16:30
Biography:
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.
