Abstract (en)
[origin: WO9704871A1] A medium pore zeolite cracking catalyst is treated with steam followed by treatment with an acidic solution to improve its butene selectivity in catalytic cracking. A process for using the treated medium pore cracking catalyst in a fluidized catalytic cracking process is also disclosed.
