IMPROVING OCTANE NUMBER AND REDUCING BENZENE CONTENT OF PRODUCT BY OPTIMIZING CATALYTIC REFORMING FEED

Abstract

Abstract: After adopting the SR-1000 semi-regeneration reforming catalyst developed by SINOPEC Research Institute of Petroleum Processing (RIPP), revamping the existing evaporator of the semi-regeneration catalytic reforming unit, reasonable controlling and optimizing the raw material properties, cutting out the precursor of benzene (including benzene and cyclohexane) before catalytic reforming, and using the combined process of isomerization of C₅/C₆ developed by RIPP,the RON of the product was increased to above 96, the blending component of gasoline whose benzene content was less than 1.0% could be produced, and the single benzene extraction unit could be shut down. The economic and social benefits were remarkable.

Key words: catalytic reforming, catalyst, SR-1000, octane number, benzene extraction, technical reform
