제목 | A study of amine-grafted zeolite : Comparison of CO2 uptake efficiency according to acid site change. |
초록 | The zeolite acid site is a very important factor in chemical reaction. The acid site distribution determines the acidity of the support, and they always show a different value depending on the various conditions such as humidity and temperature. For this reason, chemical reactions often result different yield, and the number of studies has been conducted to establish this interaction clearly. However, the interaction between physical adsorption and acid site has not been systematically studied. In this reason, the purpose of this study was to evaluate the effect of acid site on the CO2 uptake of zeolite and the amine-coated synthesis process. The acid site of zeolite was evaluated by using pyridine method, and CO2 uptake was assessed via TGA, BET and lab-scale isotherm instrument. 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”. |
