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.
