Abstract

一种蒸汽裂解制低碳烯烃催化剂及其制备方法和应用,该催化剂含有1~10重量%的铝酸钙,90~99重量%的除铝酸钙之外的其他含铝化合物载体,比表面积为80~300m<sup>2</sup>/g。该催化剂具有孔结构适宜、催化活性高、反应温度低、机械强度高等优点。以及应用该催化剂制取低碳烯烃的方法,该方法具有空速高、转化率高、低碳烯烃产率高的优点。
The invention provides a catalyst for preparing low carbon olefin by steam cracking, a preparation method and an application thereof. The catalyst by weight percent contains 1 to 10 percent of calcium aluminate, and 90 to 99 percent of other aluminiferous compound carriers except the calcium aluminate with the specific surface area between 80 and 300m<2>/g. The catalyst has the advantages of suitable pore structure, high catalytic activity, low reaction temperature, high mechanical strength and so on. The method for preparing the low carbon olefin by using the catalyst has the advantages of high air speed, high percent conversion and high yield of the low carbon olefin.
