zeolite zsm-5 Details

zeolite zsm-5,ZSM-5 molecular sieve

In petrochemistry industry, zeolite zsm-5 molecular sieve is widely used as addition of diesel hydrodewaxing catalyst and fixed bed catalytic cracking catalyst.
zeolite 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 zeolite ZSM-5 used in residuum catalytic cracking is from 25 to 30.

In chemical industry, zeolite 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 zeolite zsm-5 which SiO2/Al2O3 is from 220 to 400.
