Abstract
A catalytic cracking additive, its preparation and application thereof are provided. The catalytic cracking additive contains 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 PO, and has a micro-activity index of at least 58; the boron-containing binder comprises 70-97 wt % of AlOand 3-30 wt % of BO, 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.
