| 英文摘要 | a one-step hydrotreatment of vegetable oil combining deoxygenation and isomerization to directly produce low cloud point, high quality diesel is devised. the pt/zeolite bifunctional catalysts prepared by using sapo-11 and zsm-22 zeolites as supports are used in this process. catalytic reactions are conducted in a fixed-bed reactor under a hydrogen atmosphere. over the bifunctional catalyst, 100?% conversion of soybean oil is obtained at 357?degrees c, 4 mpa, and 1 h-1, and 80?% organic liquid yield is achieved, which is close to the maximum theoretical liquid yield. in the organic products, the alkanes selectivity is 100?% with an i-alkanes selectivity above 63?%. nh3-temperature programmed desorption (tpd), pyridine ir spectroscopy, and other characterization techniques are used to study the effect of the support acidity on the reaction pathway. over the pt/zeolite bifunctional catalyst with less strong lewis acid sites, the reaction proceeds via the decarboxylation plus decarbonylation pathway. this one-step method provides a new strategy to produce low cloud point, high quality diesel from biomass feedstock in a more economic and attractive way.
