摘要
The present invention relates to the synthesis of amine functionalized adsorbents for selective and reversible adsorption of CO2 for its separation from other gases, preferably CH4 and N2. The amine functionalized adsorbents are prepared by covalently bonding of amines to the polystyrene support for operational stability. The amines used for functionalization are selected from imidazole, N-methyl piperazine, dimethyl amine, diethanol amine, 4-hydroxymethyl pyridine and 2, 6-dihydroxy pyridine-4-carboxylic acid. The present invention also relates to the PSA process that utilizes the synthesized amine functionalized adsorbents for separation of CO2 and N2 and CO2 and CH4 in the absence of moisture.
