| Abstract: | A catalytic cracking process for production of propylene from C 4 olef ins by contacting C 4 olefins with a crystalline silicate catalyst of the ZSM- 5 molecular sieve was investigated.Three kinds of ZSM-5 molecular sieve,with crystalline diameters in the range of 0 2～30 μm,were synthesized,and corresponding activity in o lef ins catalytic cracking were determined.Small crystalline ZSM-5 molecular sieve use d as catalyst was found to be able to retard catalyst aging during olefin conver sion reaction and to have better catalyst stability.Yield of propylene increas ed with reaction temperature. |
