摘要：
Catalytic cracking catalyst compositions and processes for cracking hydrocarbons to maximize light olefins production are disclosed. Catalyst compositions comprise at least one zeolite having catalytic cracking activity under catalytic cracking conditions, preferably Y-type zeolite, which zeolite has low amounts of yttrium in specified ratios to rare earth metals exchanged on the zeolite. Catalyst and processes of the invention provide increased yields of light olefins and gasoline olefins during a FCC process as compared to conventional lanthanum containing Y-type zeolite FCC catalysts.
摘要（中）：
公开了催化裂化催化剂组合物和用于裂化烃以使轻质烯烃生产最大化的方法。 催化剂组合物包含至少一种在催化裂化条件下具有催化裂解活性的沸石，优选Y型沸石，该沸石具有少量的与沸石上交换的稀土金属比例的钇。 与常规含镧Y沸石FCC催化剂相比，本发明的催化剂和方法在FCC工艺中提供轻质烯烃和汽油烯烃的提高。
