Manganese has high oxygen storage capacity and strong reducibility, so it is widely used as a catalyst for catalytic oxidation of volatile organic compounds (VOCs) such as benzene, toluene, formaldehyde, and other environmental pollutants.manganese catalyst The most promising transition metal oxide catalysts for VOCs are manganese-based catalysts due to their superior oxygen storage and release efficiency.
The pure silica MFI zeolite, Silicalite s-1, has attracted intensive research attentions because of its superior properties in many applications.

Molecular sieve adsorbent is a form of desiccant that can be used to remove water or other liquids from gases and liquid mixtures. It is a crystalline metal aluminosilicate that has been modified to have a very specific set of pores. These pore sizes allow the molecular sieve to selectively adsorb certain molecules while leaving others to pass through. Compared to silica gel, alumina or activated charcoal, molecular sieves are more selective in the molecules that they can adsorb.

Zeolite powder is a natural mineral that is extremely beneficial for your health.zeolite powder It is one of nature’s few negatively charged minerals and it is able to trap positively charged substances like heavy metals, toxins, and free radicals in its honeycomb microporous cellular structure. It can bind and exchange these unwanted substances for healthful minerals such as potassium and sodium, and this is how it helps to detoxify the body.
Zeolites are natural and synthetic materials containing siliceous aluminosilicate frameworks with well-defined microporous structures, large specific surface areas (BSAs) and compensated cations.

In the xylene isomerization process, a mixture of C aromatics such as ortho-, meta- and para-xylenes plus ethyl benzene is converted to p-xylene by isomerization and disporportionation.
The zeolite mcm-22 is used as an alternative to alumina in the preparation of many catalysts for petroleum and chemical production.
