摘要：
Disclosed is a catalytic cracking additive, its preparation and application thereof, wherein the catalytic cracking additive comprises 10-50 wt% of a modified β zeolite, 20-85 wt% of a clay and 5-35 wt% of a boron-containing binder, based on the total weight of the catalytic cracking additive; the modified β zeolite comprises 0.1-1 wt% of CuO and 1-15 wt% of P 2 O 5 , and has a micro-activity index of at least 58; the boron-containing binder comprises 70-97 wt% of Al 2 O 3 and 3-30 wt% of B 2 O 3 , and has a pH value of 1.0-3.5. The catalytic cracking additive can significantly improve the yield of C4 olefins and the concentration of C4 olefins in liquefied gas.
