精制油氮含量对加氢裂化及其产品影响的考察

摘要

考察了高压一段串联加氢裂化工艺不同类型加氢裂化催化剂的耐氮性能、高氮条件下的催化剂活性稳定性、经历高氮运转后催化剂反应性能的恢复情况和相同裂化深度时精制油氮含量对产品分布和产品性质的影响,以及中压条件下精制油氮含量对加氢裂化转化率的影响.%Nitrogen tolerance of different hydrocracking catalysts used under high pressure once-through hydrocracking process was investigated as well as activity stability of the catalysts under high nitrogen condition,renewing of catalyst performance after running under high nitrogen condition.Effect of nitrogen content in the hydrotreated oil on yield and properties of products in the condition of same hydrocracking conversion was discussed as well as effect of nitrogen content in the hydrotreated oil on hydrocracking conversion under middle-pressure condition.
