Based on the nature of interactions between adsorbates and adsorbents, adsorption can be classified into chemical adsorption and physical adsorption. Chemical Adsorption Chemical adsorption refers to the adsorption process accompanied by chemical reactions.During chemical adsorption, adsorbate molecules react with the surface of adsorbents to form surface complexes, and the adsorption heat is...

Recently, the second-phase 14,000 Nm³/h pressure swing adsorption (VPSA) oxygen generation facility, constructed by Beijing Peking University Pioneer Technology Co., Ltd. (hereinafter referred to as "PKU Pioneer") for Chifeng Yuanlian Iron and Steel Co., Ltd.

A total of 5 steel makers in China were selected for the list, indicating the leading position...

A lithium salts factory run by Chinese miner Xinjiang Nonferrous Metal Group, that will be part of the world’s biggest integrated project for the mining, separation and smelting of lithium salts, kicked off construction in the country’s northwestern Xinjiang Uyghur Autonomous Region recently. The facility in Luofu county, Hotan prefecture will have an output of 100,000 tons of lithi...

VPSA and PSA oxygen generation equipment are primarily adopted for industrial oxygen production. Pressure Swing Absorption (PSA) oxygen generation technology is a new gas separation process that uses molecular sieves as the adsorbent to separate gas mixtures based on the difference in adsorption properties of molecular sieves for various gas molecules. With air as the raw material, i...
