This review focuses on the mechanism and driving force in the intractable gas separation
using porous adsorbents. A variety of intractable mixtures have been discussed, including …

The adsorptive generation of oxygen from air has become increasingly important in the
chemical and medical industries due to the growing demand for O 2 with high purity. Among …

The aim of this paper is to modify the X zeolite adsorbent to enhance nitrogen adsorption
capacity. To this end, a novel procedure for modification of X zeolite, including both NH 4+ …

Oxygen enrichment of intake air in internal combustion engines (ICE) is one of the effective
methods used to reduce exhaust emissions and increase performance. In this study, oxygen …

One very effective strategy for addressing global warming and transitioning to sustainable
energy sources is selective CO2 separation over H2. Porous materials, particularly zeolites …

Pressure swing adsorption (PSA) is a cost-effective and efficient method for oxygen
production. It is crucial to improve the adsorption capacity of zeolite adsorbent material to …

The aim of the present study is to investigate the effectiveness of bi-metallic LSX zeolites
containing extra-framework cations in removing and purifying O 2 from the air. Li-LSX zeolite …

The aim of the present experimental study is to reduce exhaust emissions and improve
performance by feeding a diesel engine with oxygen enriched air by the help of natural and …

Li-X zeolites have been widely used as nitrogen-selective adsorbents in oxygen
concentrators. However, the synthesis of Li-X zeolites requires an excessive amount of Li for …

Abstract Samples of Na, Li, and Ca forms of crystalline LSX zeolites with a high phase purity
and degree of crystallinity have been synthesized. The influence of replacing K+ and Na+ …
