The removal of acid gases such as CO2and H2S from natural gas is an important process. Amine process is widely applied to remove acid gas, but, it has some problems such as energy consumption, corrosion. To overcome these problems, physical adsorption with solid adsorbents is an alternative. Mesoporous materials have been generally used to capture acid gases, but they are limited because of the low selectivity and strong water inhibition. Thus, one of solution is to high adsorption capacity with small amount of amine-grafted adsorbents. In this study, to develop selective adsorbents for acid gas removal, the amine-grafted mesoporous silica was prepared by direct synthesis, impregnation. And the adsorption performance was conducted using a fixed bed reactor to examine acid gas adsorption capacity. The amine-grafted adsorbents showed the increased breakthrough and saturation time, and thus the adsorption capacity is expected to increase resulting in decreasing of adsorption reactor size. |
