中国石化长岭分公司1.7 Mt/a 加氢装置加工的渣油属于典型的高氮低硫和高铁钙含量类型,加氢反应难度大,床层压降大。第二周期采用中国石化石油化工科学研究院(简称石科院)开发的第三代 RHT 系列催化剂,在优化催化剂级配的基础上,与第一周期使用的石科院开发的第二代 RHT 系列催化剂相比,运行周期、加工量和掺渣量等指标提升明显,残炭降低效果好。

A 1.7 Mt/a residue hydrotreating unit of SINOPEC Changling Company,processed the feedstock with high S and low N,and high Fe and Ca content. The feed is difficult to be hydrotreated and easy to cause pressure drop. The 2 nd cycle of the unit adopted the 3 rd generation RHT series cata-lysts developed by SINOPEC Research Institute of Petroleum Processing with an optimized catalyst grading. The commercial results demonstrate that the cycle life,processing capacity and mixing slag quantity increase obviously by the use of the 3 rd generation RHT catalysts,compared with the second generation of RHT series catalyst,meanwhile the carbon residue conversion effect is better.
