Abstract: The vacuum gas oil (VGO) hydrotreating technology (RVHT) developed by Research Institute of Petroleum Processing was applied with matching catalysts series in a 1.8 Mt/a VGO hydrotreating unit of Maoming Company, SINOPEC, by which the hydrotreated VGO with sulfur content less than 0.1% could be obtained using inferior feedstocks under mild reaction conditions. The results showed that with the integrated process of VGO hydrotreating and FCC by using the hydrotreated VGO as the feed for FCC units, the clean gasoline blending components meeting the Guangdong Ⅳ standard could be produced with good social and economic benefits.

Key words: vacuum gas oil hydrotreating, fluid catalytic cracking, integrated process, clean gasoline
