  • Preparation method for modified molecular sieve and modified molecular sieve-containing catalytic cracking catalyst
    Patent number: 11111152
    Abstract: A preparation method for modified molecular sieve and a modified molecular sieve-containing catalytic cracking catalyst. The preparation method comprises: mixing molecular sieve slurry, a compound solution containing ions of group IIIB metals of the periodic table of elements, organic complexing agent and/or dispersing agent and precipitating agent to obtain mixed slurry containing molecular sieve and precipitates of group IIIB elements in the periodic table of elements; and drying, and roasting or not roasting to obtain molecular sieve modified by the group IIIB elements. A weight ratio of group IIIB elements calculated based on oxides to molecular sieve dry basis is equal to (0.3-10):100, a molar ratio of organic complexing agent to ions of group IIIB metals is equal to (0.3-10):1, and a molar ratio of dispersing agent to the ions of group IIIB metals is equal to (0.2-16):1. Also related to is the catalytic cracking catalyst containing the modified molecular sieve prepared according to the method.
