In order to improve heavy oil conversion and maximize high-value products, LDO-75 catalyst for residue cracking has been commercialized by adapting two core platform technologies, the shorter-channel Y zeolite with small particles and the matrix platform technology of improved coke selectivity. Laboratory evaluation results on the fixed fluidized bed (FFB) and the advanced cracking evaluation(ACE) both showed that LDO-75 catalyst could significantly resist to heavy metals and basic nitrogen, and thus enhance heavy oil conversion valuable yield. Commercial application results showed that LDO-75 catalyst could significantly improve heavy oil upgrading and enhance valuable yield, at the same time, high quality gasoline with high octane number was obtained.
