Abstract

Global warming is one of the main serious problems due to elevated index of carbon
dioxide in the atmosphere. Recently, C02 captures have been receiving significant
attention and are being recognized. Nowadays, amine based chemical absorption isone of
the famous technologies used in separation of C02. However, the liquid amine based
processes is not really preferable because ofseveral weakness such as high regeneration
energy, large equipment size, solvent leakage and corrosion problem.
Adsorption technology which is less energy intensive is known as proficient for C02
separation method since it is predicted to have low requirement of energy for porous
adsorbent regeneration while offer high productivity and selectivity. In this study,
mesoporous molecular sieve was modified using monoethanolamine for C02 adsorption
process. The materials were characterized by X-ray diffraction (XRD) and Fourier
Transform Infrared (FTIR) experiment. The carbon dioxide sorption on modified
molecular sieve was investigated using bench scale gas adsorption equipment at different
pressure and temperature. The modified mesoporous molecular sieve results in better C02
adsorption capacity compared to unmodified molecular sieve relating to the existence of
amine density in this material.
