ZSM-5 molecular sieve

In petrochemistry industry, ZSM-5 molecular sieve is widely used as addition of diesel hydrodewaxing catalyst and fixed bed catalytic cracking catalyst. ZSM-5 molecular sieve which SiO2/Al2O3 is from 38 to 40 mostly has been used as an FCC additive for decreasing olefin content in gasoline. The SiO2/Al2O3 of ZSM-5 used in residuum catalytic cracking is from 25 to 30.

In chemical industry, ZSM-5 molecular sieve is widely used as selective catalyst, such as: 1,4-diethylbenzene catalyst, xylene isomeric catalyst. In environmental protection, organic matters have been extracted by ZSM-5 which SiO2/Al2O3 is from 220 to 400.

In our factory, ZSM-5 molecular sieve is prepared by a unique non-template method and by ueing organic amine as template method. ZSM-5 molecular sieve was honored with second prize of national invention.
