Product Introduction
MCM-22 is a novel molecular sieves produced by our company. It has a structure of MWW and two kinds of independent channel system, one channel system contain large super cages of lauronitrile ring, these super cages by coincide hexatomic ring, one upone another, run through approximate oval-shaped windows of deca ring; another channel system is a two-dimension sine wave channel its effective bore diameter is deca ring, around which is coincide hexatomic ring which is linked together with super cages.
MCM-22 possessed a unique pore channel structure, both with acid catalysis characteristic. It has good stability of hydrothermal, strong of adsorb capacity, large of BET, can be used in alkylate, environmental protection, gasoline modification, catalytic cracking, isomerization and dismutate of aromatic compound, isomerization, hydration and polymerization of olefin etc area of catalysis.
