Abstract

Abstract: The commercial application of RN-32V catalyst in the 2.3 Mt/a hydrotreating unit of Fujian Refining and Petrochemical Company was introduced processing feedstock containing deasphalted oil (DAO) and coker gas oil (CGO), which was high in asphaltene, carbon residue and metal contents, as well as with high FBP. The assessment of performance at the initial stage showed that using RN-32V catalyst, under the process conditions of a hydrogen partial pressure of 14.04 MPa, an average catalyst bed temperature of 384.6 ℃ and LHSV of 1.11 h-1, the sulfur and nitrogen contents of the treated feed dropped significantly, which improved the feed quality for FCC unit.

Key words: catalyst, hydrotreating , deasphalted oil, coker gas oil
