CF4의 동적흡착특성 연구
A Study of Dynamic Adsorption Characteristics of CF4
PFC(PerFluoroCompounds) are used as CFC(ChloroFluoroCarbons) substistutes. PFC are highly stable gases with long atmospheric lives and are considered significant global warming compounds. Therefore, PFC gas have been targeted by governments worldwide for significant reduction in emission. One way to control the emission of PFC gases is adsorption. In this study, the adsorption behavior of CF4 on activated carbon in adsorption column was studied by breakthrough curve analysis. Effects of CF4 concentrations in feed gas and pressurization condition were investigated. Desorption curves with various N2 flow rates and feed compositions were obtained.
