MTT zeolite ZSM-23 structure has a topological framework. Its skeletal structure contains both five-membered rings, six-membered ring and ten-membered ring, the one-dimensional channel by ten-membered rings composed of mutual non-crosslinked parallel channels, no similar cross-MFI structure zeolite pore structure. Ten yuan ring opening of three-dimensional wavy, teardrop-shaped cross-section. Note: post-processing can be divided in different ways sodium type, potassium type, SiO2 extruded bar, Al2O3 extruded bar type.
ZSM-23 zeolite pore structure due to the unique and strong surface acid properties, in many catalytic reactions exhibit high catalytic activity and selectivity. Mainly used for olefin oligomerization, olefin / paraffin cracking, alkylation and isomerization of aromatics, straight chain hydrocarbon skeleton isomerization, separation and adsorption desulfurization reactions, olefin oligomerization, and in particular in the catalytic cracking of olefins aspects has good catalytic performance.
