蜡油加氢预处理RVHT技术开发进展及工业应用

摘要

介绍了中国石化石油化工科学研究院的蜡油加氢预处理RVHT技术开发进展及工业应用情况.RVHT技术配套加氢处理催化剂RN-32V以及RVS-420具有优异的加氢脱硫脱氮反应性能.通过个性化的催化剂级配和反应工艺参数优化,可以拓宽RVHT技术的原料油适应性.应用RVHT技术生产催化裂化进料,可有效降低催化裂化进料催化裂化汽油硫传递系数,为生产清洁汽油创造了有利条件.%The recent progress and commercial application results of vacuum gas oil (VGO) hydro-treating technology (RVHT) developed by Research Institute of Petroleum Processing were introduced. Hydrotreating catalysts RN-32V and RVS-420 showed excellent HDS and HDN performance both in pilot plant test and commercial application. Through proper catalysts combination and reaction parameters optimization,the feedstock adaptability of RVHT technology was widen. Low sulfur content FCC feedstock provided by RVHT technology could reduce the sulfur transfer rate of FCC feed and FCC gasoline, it is helpful for producing clean gasoline.
