Abstract: For clean gasoline production, a 1.5 Mt/a RFCC unit was successively revamped by ARFCC technology and MIP-CGP technology to reduce the olefin content of gasoline. The revamping, operation, product slate and property, as well as energy consumption of these two technologies were reviewed in this paper. It was found that compared with base case, both technologies could meet the demand of producing clean gasoline, yet MIP-CGP technology exhibited more technical advantages. Adopting MIP-CGP technology, the capacity of the unit expanded to 1.7 Mt/a, the residue blending ratio could be in the range of 15%—53%, and the quality of gasoline was improved significantly. When residue blending ratio was below 35%, the olefins volume fraction of gasoline could be kept below 32%, RON maintained over 90 and the gasoline induction period was prolonged remarkably. Besides, the energy consumption of the unit with MIP-CGP technology was lower than the other cases.
