摘要
以酸性试剂为萃取剂,碱为反萃取剂,对抚顺页岩原油中氮化物尤其是碱性氮化物的脱除进行了研究。结果表明,增大剂油质量比、提高反应温度、延长反应时间及沉降时间均有利于页岩油中碱性氮化物的脱除,同时油品的质量也得到了一定程度的改善。当以酸性试剂A为萃取剂,剂油质量比为1∶1,反应温度为60℃,反应时间为20 min,沉降时间为4 h时,页岩油中的碱氮脱除率可达96.04%,总氮脱除率达38.25%,页岩油的收率为97.18%。
Removal of nitrogen compounds especially basic nitrogen compounds from Fushun shale oil with acidic reagent as extraction reagent and lye as back-extraction reagent was investigated.The results show that removal rate of basic nitrogen compounds increased with the increasing mass ratio of agent to oil,reaction temperature,reaction time and settling time respectively,at the same time the quality of shale oil is improved in a way.When mass ratio of agent to oil ratio was 1∶1,reaction temperature was 60 ℃,reaction time was 20 min and settling time was 4 h with acidic reagent A,removal rate of basic nitrogen compounds is up to 96.04%,and that of total nitrogen compounds is up to 38.25%,the yield of shale oil is 97.18%.
