Abstract: The catalysts of LDC series use new-type Y-shaped molecular sieve and high octane number shape-selective molecular sieve as active components and are combined with the semi-synthetic catalytic cracking catalyst prepared by means of the heavy metal pollution resistant technology. This product can increase olefin content in FCC gasoline so as to provide high-quality raw materials for subsequent gasoline hydro-desulfurization and light gasoline etherification unit. The catalyst has good heavy oil cracking performance and the flexibility to adjust the variable yield of LPC, improving catalytic gasoline octane number. It also has an appropriate density, good abrasive resistance and good fluidizing performance. The series is characterized for its strong heavy oil conversion ability, low coke yield, high yield of light oil, heavy metal pollution resistant property and higher gasoline octane number. The catalysts are suitable for conventional catalytic and heavy oil catalytic cracking units.
