糠醛精制抽余油生产环烷基橡胶增塑剂的工艺优化研究
|
摘要
以绥中36-1减三线糠醛精制抽余油为原料,采用加氢处理+临氢降凝+补充精制三段加氢组合工艺,通过催化剂级配及工艺条件优化,制备环烷基橡胶增塑剂。结果表明:在加氢处理催化剂RL-1、临氢降凝催化剂SDD-800、加氢补充精制催化剂LN-5、三段的体积空速分别为1.3,0.8,0.6 h~(-1),加氢处理及临氢降凝温度均为340℃,加氢补充精制温度为240℃时,可以得到满足HG/T 5085—2016《橡胶增塑剂环烷基矿物油》标准中产品N4010指标要求的环烷基橡胶增塑剂,收率超过90%。净利润较抽余油直接出售增加1 370元/t,潜在经济效益显著。
Furfural raffinate oil with low nitrogen and aromatics content is suitable to produce colorless and low aromatic rubber plasticizer.In this paper,we use raffinate oil from SZ36-1 No.3 vacuum cut as raw material to produce naphthenic rubber plasticizer by the combined process of hydrotreating(catalyst RL-1),hydrodewaxing(catalyst SDD-800)and hydrofinishing(catalyst LN-5).The LHSV of RL-1,SDD-800,LN-5 was 1.3,0.8,0.6 h~(-1),respectively.The reaction temperature of hydrotreating and hydrodewaxing were both 340 ℃ and the temperature of hydrofinishing was 240 ℃.The experimental results showed that naphthenic rubber plasticizer produced met the N4010 indexes of HG/T 5085—2016"Rubber plasticizer-naphthene base mineral oil",the yield of the product was over 90%.The net profit increases by 1 370 RMB/t compared with the direct sale of the residual oil.The potential economic benefits are significant.
