实验以Al-PILM,FeAl-PILM,β沸石和Y型分子筛为载体制备了NiW加氢裂化催化剂,对页岩油全馏分进行加氢裂化催化实验。对所得的产品油于实沸点蒸馏装置上进行馏分切割,并对各个馏分进行分析。结果表明:四种催化剂对页岩油都有明显的加氢裂化性能,轻馏分的收率较原油有很大提高,最高收率分别,<160℃为2.8%,160～370℃柴油为59.5%,所得160～370℃柴油的40℃运动黏度为3.248～3.324mm2.s-1,凝点-2～-3℃,闪点82～85℃,十六烷值62.3～63.4,20℃密度0.8305～0.8422g.cm-3,符合欧Ⅳ柴油排放指标,可作为生产优质柴油的原料。
Experimental NiW hydrocracking catalysts were prepared from Al-PILM, FeAl-PILM, β-zeolite and Y-type zeolite to catalyze the hydrocracking of shale oil fractions. The resulting product oil was subjected to fractionation on a solid boiling point distillation apparatus, and the individual fractions were analyzed. The results show that all four catalysts have obvious hydrocracking properties for shale oil. The recovery of light fraction is much higher than that of crude oil, with the highest yield of 2.8% at <160 ℃ and 59.5 at 160 ~ 370 ℃ respectively %, The resulting 160 ~ 370 ℃ diesel 40 ° C kinematic viscosity of 3.248 ~ 3.324mm2.s-1, freezing point -2 ~ -3 ℃, flash point 82 ~ 85 ℃, cetane number 62.3 ~ 63.4,20 ℃ Density 0.8305 ~ 0.8422g.cm-3, in line with Euro Ⅳ diesel emission targets, can be used as raw materials for the production of high-quality diesel.
