Abstract: The commercial application of FCC catalyst SGC-1 for improving gasoline yield in the 2nd RFCCU of Sinopec Yanshan Petrochemical Company was presented. The results show that the yield of gasoline increases to 47.57%, 47.05%, and 47.10%, i.e. the growing range of 4.56, 4.04, and 4.09 percentage points, respectively for three solutions of maximizing gasoline yield, maximizing feedstock flow rate, and maximizing blending residue ratio. The selectivity of dry gas, gasoline, and coke are improved, especially the selectivity of gasoline increases significantly. While the yield of total liquid products remained steady. SGC-1 catalyst has significant advances in increasing the yield of gasoline, good feedstock adaptability and dry gas selectivity. It can meet the requirement of improving product distribution of FCC unit.
