Online TG-FTIR characterization of ethanol in situ catalytic reaction
摘要
Abstract
Online TG-FIIR characterization of ethanol in situ catalytic reaction over Ag/K2O/Al2O3 or Cu/K2O/AI2O3 using a carrier gas carrying ethanol as feed gas was made. The effect of the temperature of transfer line from TG to FITR on the separation and identification of the unreacted reactant and products was investigated. The results showed that the temperature of transfer line had a significant influence on the identification of products. Due to the difference in boiling points, the unreacted reactant and products could be separated by controlling the temperature of transfer line. Therefore, the products could be effectively identified and the activity of the catalysts could be evaluated. Compared with Cu/K2O/Al2O3, Ag/K2O/Al2O3 exhibited an improved conversion of ethanol and activity.关键词
