Measurement and interpretation of unary supercritical gas adsorption isotherms in micro-mesoporous solids

Ronny Pini et al.

Summary: Gas adsorption at high pressures in porous solids is often quantified by the excess amount adsorbed. This study compared supercritical CO2 adsorption isotherms on three adsorbents with different microporosity fractions and discussed the challenges in extracting quantitative information on the properties of the adsorbed phase. The data revealed pore-size dependent adsorption behavior and the potential to complement traditional textural analysis by physisorption.

A study on factors influencing CO2 adsorption by coal

Xuefeng Wang et al.

Summary: The study found that moisture, pH value, and coal rank all affect the adsorption capacity of coal for CO2. Acid treatment and alkaline treatment can enhance the adsorption capacity of coal, while the presence of moisture inhibits the adsorption process.
