摘要： 应用酸性复合溶剂络合法脱除焦化蜡油中的碱性氮化物。试验结果表明，络合剂与助剂等体积加入，在剂油体积比为0.0150，反应温度50℃，反应时间为2.0min，静置时间为20min时，焦化蜡油中的碱性氮化物能够被有效地脱除，脱除率为90.79%，油品收率为94.53%。所筛选出的中和剂能够有效地除去残余的溶剂，并且具有破乳功能，最终生成物对环境无污染。精制油经过二次处理后可直接进入催化裂化装置。

Abstract: Acidic compound solvent was used to remove basic nitrogen compounds (BNC) in coker gas oil by complexation reactions and the process conditions were investigated in the laboratory. The test results showed that the BNC in coker gas oil could be effectively removed under the conditions of a volume ratio of agent to oil of 0.015, a volume ratio of complexation agent to promoter of 1, a reaction temperature of 50 °C, a reaction time of 2 min and a standing time of 20 min, the BNC removal rate reached 90.79% and the oil yield was 94.53%. The selected neutralizer could remove the residual solvent and also possessed good demulsification function. The treated oil could be used as FCC feedstock after another treatment.
Key words: basic nitrogen compounds, complexation reactions, coking process, wax oil
