【 摘 要 】

Microporous molecularsieves of type Y, Beta, ZSM-5, ZSM-12 and ZSM-35, and mesoporous molecular sievesof type MCM-41 and MCM-48, and these sieves modified with triethanolamine andethylenediamine were obtained and characterized by XRD, FTIR, TGA and nitrogenadsorption. The adsorption tests were performed by the gravimetric method undera stream of CO2 at ambient temperature and pressure. The adsorbentsstudied showed maximum adsorption capacity of carbon dioxide in the range of13.1 to 85.5 mg of CO2 per gram of adsorbent.
