Molecular sieve carrier has uniform micropores, and its pore size is equivalent to that of ordinary molecules Inorganic microporous materials composed of AL2O and alkaline metals or alkaline earth metals, with the inner pore volume accounting for 40-50% of the total volume and specific surface area of 300-1000m2/g, have the characteristics of high temperature resistance, non flammability, good thermal stability and hydrothermal stability. The microporous molecular sieves with the pore size below 2nm and mesoporous molecular sieves with the pore size of 2-50nm (macroporous molecular sieves with the pore size above 50nm), Mesoporous molecular sieves have high specific surface area, regular and orderly pore structure, narrow pore size distribution, continuous and adjustable pore size and other characteristics, which make them play a role in the adsorption and separation of macromolecules that are difficult to complete for many microporous molecular sieves, especially in catalytic reactions. Mesoporous materials can generally be divided into two categories: silica based and non silica based. Silica based mesoporous molecular sieves have narrow pore size distribution, regular pore structure, mature technology and many researches. Silica based mesoporous molecular sieves can be used in catalysis, separation and purification, drug embedding and sustained release, gas sensing and other fields. Non silica mesoporous molecular sieves mainly include transition metal oxides, phosphates and sulfides. It is widely used in adsorption, catalyst loading, acid catalysis, oxidation catalysis (such as methanol olefinization, hydrocarbon oxidation) and other fields. Our company now produces molecular sieve products: microporous molecular sieve, mesoporous molecular sieve. According to the different components of organic waste gas, the product is equipped with molecular sieve materials with different properties and pore sizes to achieve targeted and selective treatment of organic waste gas, meet the design requirements and emission standards.
