Abstract: The industrial application of ZCG-1 catalyst in the RFCC unit of Beijing Yanshan Company，SINOPEC was introduced. The results of application indicate that ZCG-1 catalyst shows excellent residue cracking ability, resistance to heavy metal contamination and good coke selectivity, especially gasoline selectivity. When the feedstock contains 50 % (w) residue, the gasoline yield reaches 48%-50 % (w), increased by 6.0 percentage points than the former catalyst VRCC-1 and the liquid yield maintains at 82%-83% with a good product distribution and a remarkable economic benefit.

Key words: increasing production of gasoline, catalytic cracking catalyst, residue, product distribution
