|제목||Effect of silica-alumina ratio on zeolite for carbon dioxide adsorption from nature gas|
|초록||In a liquefied natural gas (LNG) plant, the pre-treatment process for removal of impurities such as CO2, H2S and Hg etc. have been required. There are several separation technologies such as absorption, adsorption and membrane for the CO2 pre-treatment process. In this study, the X and Y zeolites with FAU type structure for CO2 adsorption was selected. Also the effect of different silica alumina ratio (SAR) was evaluated. The SAR could controlled the surface area and pore volume, and they were attributed to the ability of CO2 adsorption. The CO2 adsorption performance was assessed by BET, TGA and isotherm adsorption system.
This study has been conducted with the support of the Ministry of Trade, Industry and Energy as “Development of engineering package and empirical technology for mobile type small onshore LNG plant” (10077506).
