Preparation and characterization of dry solid sorbent based on hydroxy alkyl amidine and polyethyleneimine/silica hybrids for CO2 capture |
| 초록 |
Hydroxy alkyl amidine (HAM) derivatives can capture and store CO2 in quantitative manner and absorption/desorption CO2 reversely under dry conditions. The HAM was impregnated into porous silica particles to form solid CO2 sorbents, which can help to release the heat of reaction and to enhance the CO2 capture efficiency by increasing surface area. We study dry absorbent which was prepared with HAM and porous silica, such as MCM-41 or SBA-15, to evaluate the performance of the material in terms of CO2 absorption/desorption. Here we present CO2 capture and release behavior at various condition when we add polyethyleneimine to HAM/silica hybrids. |
