Zsm-5 Zeolite

Synthetic ZSM-5 Zeolite Molecular Sieve as MTP Catalyst Carrier For Petrochemical Industry ZSM-5 Zeolite The ZSM-5 type zeolite produced by means of a template agent free hydrothermal crystallization method is featured with high relative crystallinity,wherein the relative crystallinity is no less than 90%,the SiO2/Al2O3 molar ration is no less than 25,and the Na2O is no more than 0.1%. ZSM-5 Quality Control Targets Detailed Product Description Product Name: Zeolite ZSM-5 Mole Ratio: 15-1000 Cas No.: 308081-08-5 Cl-: Max90ppm SO4: Max0.4 BET: 330-360 Specifications Mole Ratio: 15-1000 Nominal Cation Form: Ammonium/Hydrogen Products SiO2/Al2O3Mole Ratio Nominal Cation Form Na2O Weight % Surface Area, m2/g JL 01 25 Sodium/Hydrogen 0.05 340 JL O2 30 Sodium/Hydrogen 0.05 340 JL 03 50 Sodium/Hydrogen 0.05 340 JL 04 80 Sodium/Hydrogen 0.05 340 JL 05 280 Sodium/Hydrogen 0.05 340 Na2O Weight %: 0.05 Surface Area, m2/g: 340 Hydrophobic ZSM-5 having a high silica to alumina ratio, the smaller the surface charge density. The water molecule is polar, so you will not ZSM-5 is adsorbed. Although water molecules smaller than the diameter of n-hexane, but the amount of adsorption of n-hexane ZSM-5 is generally greater than water. Easy to coke ZSM-5 V-shaped aperture effective, pore size and bending, preventing a large condensate formation and accumulation. Meanwhile, ZSM-5 framework is no greater than the bore of the cavity (cage) exist, so limiting the formation of large molecules from the secondary condensation reactions. So that the possibility of ZSM-5 catalyst coke is reduced. ZSM-5 for an alkyl aromatics into the tunnel barrier is formed, and thus the reaction process it can not continue to react in smaller pores, the final condensation formed coke. ZSM-5 so much slower than the rate of coke deposition and Y-type mordenite, difference of almost two orders of magnitude. Capacity of ZSM-5 zeolite carbon content is higher. Excellent shape-selective selectivity Zeolite molecular sieve as catalyst, only smaller than the hole crystal molecules can catalyze the reaction out of control pore size crystalline zeolite suffering zeolite catalyst size and shape of reactant and product molecules showed great selectivity. Pore system of ZSM-5 zeolite having a 10-MR constituted medium size orifice diameter, it has a good shape-selective selectivity.

Zsm-5 zeolite could be used for petrochemical industry, fine chemical industry and other fields because of its special three-dimensional cross straight pore canal, special shape-selective crackability, isomerization and aromatization ability. Presently, they can be applied to the fcc catalyst or additives that can improve the gasoline octane number, hydro/nonhydrodewaxing catalysts and the unit process xylene isomerization, toluene disproportionation and alkylation. ging the silica-alumina ratio according to your requirements.
