Abstract: The research and application of technologies related with FCC feed pre-hydrotreatment developed by Research Institute of Petroleum Processing (RIPP) were introduced including RHT technology and its second generation catalyst, RVHT technology and RN-32V catalyst, and newly developed hydrotreating VGO blended with residue technology (DVHT). Special attention was given to the commercial application of RICP technology, an innovated bi-direction integrated technology of residue hydrotreating and catalytic cracking. The results of pilot plant test and commercial application indicated that FCC feed pre-hydrotreating technologies developed by RIPP were highly reliable, adaptable to various feedstocks and stable to long-term running.

Key words: vacuum gas oil, petroleum residue, hydrotreating, catalyst
