高黏度聚α-烯烃合成油加氢技术研究

摘要

采用中国石油石油化工研究院开发的Pt-Pd/Al2O3加氢精制催化剂对聚α-烯烃PAO40粗产品进行了加氢精制.结果表明:在反应温度240~280 ℃、反应压力4.0~8.0 MPa、体积空速0.1~0.4 h-1、氢油体积比300∶1的工艺条件下,PAO40加氢产品的芳烃含量达到国外同类优秀产品水平;PAO40加氢产品经光照30天后不变色,具有较好的光安定性.%The PAO40 crude product was hydrogenated using Pt-Pd/Al2O3 catalyst developed by the Petrochemical Research Institute of PetroChina and the optimal conditions were determined.The results show that under the optimized operating conditions of hydrofining which are 240-280 ℃,4.0-8.0 MPa,LHSV of 0.1-0.4 h-1 and hydrogen/oil volume ratio of 300,the hydrogenated PAO40 has a similar aromatic content with the PAO40 products abroad.No Saybolt color changes of the hydrogenated PAO40 are observed after light test for thirty days,indicating its good light stability.
