摘要：

This study developed a simple model to investigate effects of important operating parameters on performance of a bubbling-bed adsorber and regenerator system collecting CO2 from flue gas. The chemical reaction rate was used with mean particles residence time of a reactor to determine the extent of conversion in both adsorber and regenerator reactors. Effects of process parameters - temperature, gas velocity, solid circulation rate, moisture content of feed gas - on CO2 capture efficiency were investigated in a laboratory scale process. The CO2 capture efficiency decreased with increasing temperature or gas velocity of the adsorber. However, it increased with increasing the moisture content of the flue gas or the regenerator temperature. The calculated CO2 capture efficiency agreed to the measured value reasonably well. However the present model did not agree well to the effect of the solid circulation rate on CO2 capture efficiency. Better understanding on contact efficiency between gas and particles was needed to interpret the effect properly.
