Abstract: The recent progress and commercial application results of vacuum gas oil (VGO) hydrotreating 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.

Key words: RVHT technology, vacuum gas oil hydrotreating, clean gasoline
