China’s pressure swing adsorption (PSA) oxygen production technology originated in the 1970s. After decades of development, the technology has been continuously upgraded, and high-efficiency lithium-based molecular sieves for oxygen production have been industrialized and widely applied. Latest research in the field shows that optimizing adsorbent manufacturing, improving adsorption tower d...

The biggest challenge facing oxygen-enriched blast furnace operation is oxygen supply. Instability in the oxygen enrichment rate of blast furnaces at integrated iron and steel works has long been a critical issue, which is highly detrimental to the stability of blast furnace conditions and the performance of coal injection. Practical Challenges A Chinese iron and steel enterprise commissione...

In response to the call from the Ordos municipal government to promote the translation and implementation of Peking University's scientific and technological achievements in Ordos, and leveraging the University's profound research heritage along with its own industrial capabilities, Peking University Pioneer Technology Co., Ltd. (hereinafter “PKU Pioneer”) was invited as a core t...

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...
