缩合法脱除汽油中噻吩类硫化物的研究

将脱硫剂CD-1与Amberlyst-15酸性树脂配合使用，可以有效的将汽油中的噻吩类硫化物经缩合反应转化为沸点超出汽油流程的产品，从而通过蒸馏的方法脱除。模型汽油缩合法脱硫获得的优化实验条件为：反应温度80℃，反应时间20min，脱硫剂与模型汽油质量剂油比为1∶100，催化剂与模型汽油质量剂油比为1∶10，油品中噻吩硫化物的转化率可达100%。汽油中的碱氮类化合物对Amberlyst-15的催化性能有明显影响，会造成催化剂失活。

Removal of thiophenic sulphide compounds from gasoline by condensation with a desulfurizing agent

Thiophenic sulfur compounds can be effectively converted by condensation with CD-1 desulfurizing agent catalyzed by Amberlyst-15 acid porous resin.The thiophenes are transformed to compounds with a boiling temperature beyond the gasoline distillation range,and thus the sulfur compounds can conveniently be removed by distillation.The optimum reaction conditions for desulfurization of a model gasoline sample were found to be a temperature of 80℃ a reaction time of 20 minutes,condensation agent-to-oil mass ratio of 1∶100,and catalyst-to-oil mass ratio of 1∶10,giving a conversion of thiophene of ~100%.Basic nitrogenous compounds in gasoline had an adverse effect on the catalyst.The condensation desulfurization methods exhibited high sulfur removal efficiency and has promising prospects for practical application.
