摘　　要：考察了减压蜡油在加氢裂化条件下,转化深度与产物变化情况,通过精细切割与表征探究烃类分布规律。结果表明:加氢裂化产物中<220℃组分收率随转化率提高而增加,>400℃组分收率随转化率提高逐渐降低。烃类组成变化符合多环芳烃优先进行加氢转化并向轻组分迁移、链烷烃得以保留的规律,明确了加氢裂化产品收率和质量的相互关系。The conversion depth and product changes of Vacuum wax oil under hydrocracking conditions were investigated,and the distribution patterns of hydrocarbons were explored through fine cutting and characterization.The results showed that the yield of <220 ℃ components in hydrocracking products increased with increasing of conversion rate,while the yield of >400 ℃ components gradually decreased with increasing of conversion rate.The change in hydrocarbon composition conformed to the principle that polycyclic aromatics were preferentially hydrogenated and migrated towards light components,while alkanes were retained,clarifying the relationship between the yield and quality of hydrocracking products.
