| Abstract: |
| An efficient CO2 composite collector was prepared by composite method using primary amine and enamine as raw materials, the changes of the reagent before and after the reaction of the collector with CO2 were preliminatively determined by FT-IR and ionic analysis. The optimum concentration, reaction temperature, composition ratio and flue gas concentration were determined by optimizing the process parameters. The capture efficiency is above 99% and the effective capture time is 300 min under the optimum conditions including the concentration of efficient composite collector of 30%, the intake concentration of 20%, and the reaction temperature of 30 ℃. The collector can be recycled after high temperature desorption. |
