氢化6#溶剂油中芳烃的方法研究

Study on the hydrogenated method of aromatics in 6# solvent oil

通过镍铝催化剂对6#溶剂油进行氢化处理,在反应釜进行氢化反应,对氢化压力、氢化温度、氢化时间、搅拌速度、催化剂添加量进行单因素实验和响应面优化实验,得出最佳工艺参数为:氢气压力为0.61MPa,温度为81℃,时间为70min,搅拌速度为150r/min,催化剂添加量为3%,脱芳率达到96.3%,氢化前溶剂油中芳烃含量为15500μg/g,氢化后的溶剂油中芳烃含量<100μg/g。有效地降低了浸出油脂中的芳烃含量。

The 6# solvent oil was hydrogenated by nickel-aluminum catalyst in the conventional hydrogenation reactor.The single-factor tests and the response surface methodology was used to confirm the optimal conditions of hydrogenation such as hydrogenation pressure, hydrogenation temperature, hydrogenation time, stirring speed and catalyst addition.The optimal condition of the hydrogenation： hydrogenated pressure was 0.61MPa, the temperature was 81℃, the time of reaction was 70min, stirring speed was 150r/min and the catalyst was 3%, dearomatization rate was 96.3%.Before the hydrogenation the content of aromatic hydrocarbon existing in the solvent oil was 15500μg/g while reduced to less than 100μg/g by hydrogenated.This method effectively reduced the content of aromatic in the leachinQ oil.
