Strong adsorption capacity: Even if the composition concentration of the gas is very low, it still has the adsorption capacity and a large adsorption capacity at a higher temperature. Under the same temperature conditions, the adsorption capacity of molecular sieves is larger while other adsorbents are greatly affected by temperature. Because of the above advantages, molecular sieves have become a very good adsorbent, widely used in the production of basic organic chemicals and petrochemicals. In the treatment of harmful gases, it is also commonly used in SO2, NOX, CO, CO2, NH3, CCI4, Purification of water vapor and gaseous hydrocarbon waste gas.

It can be regenerated at high temperature, with high regeneration efficiency and high safety. The use of shaped molecular sieve as the adsorbent for waste gas treatment will become the mainstream. The technology of molecular sieve as a carrier has been widely used abroad. Molecular sieves can be designed and applied according to different pollutant concentration and particle size.

Features

The molecular sieve carrier has uniform micropores, and the pore molecular sieve carrier has uniform micropores, and its pore size is equivalent to the general molecular size. It is an inorganic microporous material composed of SIO2, AI2O and alkaline metals or alkaline earth metals, and its inner pore volume accounts for the total volume. The specific surface area is 300-1000㎡/g. It has the characteristics of high temperature resistance, non-flammability, good thermal stability and hydrothermal stability. Its pore size is below 2μm for microporous molecular sieve, and 2-50μm for medium Porous molecular sieve (large pore molecular sieve above 50μm), mesoporous molecular sieve has extremely high specific surface area, regular and orderly pore structure, narrow pore size distribution, continuously adjustable pore size, etc., making it difficult to complete in many microporous molecular sieves It plays a role in the adsorption and separation of large molecules, especially in catalytic reactions.
