摘要
合成了一种应用于重油催化裂化的新型表面活性剂,考察了反应温度、反应时间、酸醇摩尔比和催化剂投入量对该产品酸值、皂化值的影响,从而确定最佳反应条件:反应温度为135℃,反应时间为3 h,酸醇摩尔比为1∶1.2,w(催化剂)为0.4%。对辽河蜡油的强化裂化实验表明,添加该表面活性剂后产品分布得到了较大的改善,轻油收率提高,焦炭和干气产率下降。
The surfactant which was applied to catalytic cracking of heavy oil was synthesized. The effects of reaction temperature, reaction time, the mixture ratio of raw material, as well as the input amount of catalyst on acid value and saponifying value of this product were studied. The optimal reaction conditions were determined： Reaction temperature is 135 ℃ ; time is 3 h; the ratio of raw material is 1 ： 1.2; ω（catalyst） is 0.4%. Intensified FCC shows that the surfactant improves distribution of the product, increased yield of light oil, decreased productivity of coke and dry gas.
