Abstract: The commercial application of RCGP-1 catalyst for improving gasoline yield in the 3rd MIP-CGP unit of SINOPEC Yanshan Company was presented. The result showed that the yield of gasoline increases by 2.01percent points, the RON and MON increases by 1.3 and 0.4 respectively; the yield of LPG and total liquid increases by 2.22 and 0.83 percent points, respectively; the yield of LCO decreases by 3.41 percent points, while the yield of dry gas is reduced and the coke selectivity is similar to the blank one. RCGP-1 catalyst showed significant advances in increasing bottoms cracking and anti-metal contamination ability along with improving the gasoline octane barrels significantly.

Key words: cracking catalyst, gasoline , octane number, commercial application
