| 英文摘要 | liquid fuels derived from renewable biomass are of great importance on the potential substitution for diminishing fossil fuels. the conversion of sorbitol (a product of biomass-derived glucose hydrogenation) into liquid alkanes such as pentane and hexane over the ni/hzsm-5 catalysts with or without mcm-41 addition was investigated in the presence of hydrogen in water medium. the production distribution of sorbitol hydrogenation can be controlled by adjusting the acidity of the catalyst. the scission of c-c bond in the sorbitol molecule into light c-1-c-4 alkanes was mainly carried out over ni/hzsm-5 containing strong bronsted acid sites, while c-o bond scission into heavier alkanes was dominated over the catalysts added by mcm-41 containing weak lewis acid sites. the sorbitol conversion and total liquid alkanes selectivity were found to be 67.1% and 98.7% over 2%ni/hzsm-5 modified by 40 wt% of mcm-41, whereas the corresponding value was 40% and 35.6% over 2%ni/hzsm-5 in the absence of mcm-41. the effect of mcm-41 on the structure, acidity, and reducibility of ni/hzsm-5 was investigated by using xrd, py-ir, ir, and h-2-tpr. meanwhile, the resistance of carbon deposition over the catalyst modified by mcm-41 was studied by using tg-dsc technique. mcm-41 was found to have a positive interaction with hzsm-5 on the modulation of its structure properties and acidity, accompanying by the improvement on the reducibility of the catalyst. in addition, mcm-41 can distinctly decrease carbon deposition on the catalyst surface. these roles can favor the selective hydrodeoxygenation of c-o bond in the sorbitol molecule to generate liquid alkanes.
