CO2 adsorption on systems involving ethylenediamine impregnated on nanoporous materials

摘要

MCM-41 and MCM-48 materials were synthesized by the hydrothermal method, calcined and modified with ethylenediamine (EDA) by wet impregnation method. The X-ray diffraction patterns showed characteristic peaks of highly ordered MCM-41 and MCM-48 nanoporous materials, even after impregnation with amine. The MCM-41 and MCM-48 materials showed N-2 adsorption isotherms type IV and BET surfaces areas higher than 1000 m(2) g(-1). The carbon dioxide adsorption tests were carried out at room temperature in a magnetic suspension microbalance. The materials presented good performance for CO2 capture, being favorable for applications where medium and high pressures are required.
