The liquid fuel (made of C-5/C-6 alkanes) was obtained directly from the hydrogenolysis of microcrystalline cellulose (MCC) with Ir-VOx/SiO2 combined with HZSM-5 as the composite catalyst in a biphasic system (n-dodecane + H2O). The performance of the catalyst was investigated by carrying out a series of experiments using various V/Ir molar ratios, catalyst dosages, reaction temperatures, reaction time, hydrogen pressure and substrates. At the optimized conditions, the cellulose was almost completely converted, and at the same time, a high C-5/C-6 yield of 85.1% was obtained at 210 degrees C for 24 h and 6 MPa with the V/Ir molar ratio being 0.13. These results not only proved that Ir-VOx/SiO2 (V/Ir = 0.13) has excellent performance for the hydrogenolysis of MCC to liquid alkanes, but also indicated that vanadium is a good metal promoter for iridium. In addition, it was proven the C-5/C-6 alkanes were obtained via sorbitol through the combined effect of Ir-VOx/SiO2 and HZSM-5.
