ZSM-5 is a kind of aluminosilicate zeolite with high Si / Al ratio and three-dimensional straight through pore structure, which was developed by Mobil company in 1972. Because of its regular pore structure, large specific surface area, high hydrothermal stability, good ion exchange performance and adjustable surface properties, ZSM-5 is widely used in the fields of adsorption, catalysis, ion exchange and pollution disposal.
For example, as an adsorbent, ZSM-5 can be used in wastewater treatment, gas separation and enrichment;
In industry, the most mature application of ZSM-5 is fluidized bed catalytic cracking (FCC),
In addition, ZSM-5 showed excellent catalytic activity in methanol to gasoline (MTG), methanol to aromatics (MTA) and methanol to propylene (MTP);
The introduction of metal ions into ZSM-5 molecular sieves by ion exchange method can show more extensive application performance and potential.
