| Résumé: | An increase in power demand is one of the key reasons for the global warming problems due to the increase of greenhouse gas emissions. Carbon dioxide (CO2) is the main greenhouse gas emitted into the atmosphere. CO2 capture technology becomes an alternative solution to reduce CO2 emissions. There are many processes for CO2 capture technology. Among these, CO2 adsorption using solid sorbent has been wildly received attention. Most of the study was focused on the adsorption performance of solid sorbent. However, only a few studies were focusing on the regeneration of solid sorbent. This study investigated the effects of regeneration temperature and pressure on the regeneration rate of non-modified and modified K2CO3/γ-Al2O3 with monoethanolamine (MEA). The results showed that an increase in regeneration temperature and a decrease in regeneration pressure enhanced the regeneration rate of non-modified and modified K2CO3/γ-Al2O3. Furthermore, the experimental data of the regeneration rate was fitted to Avrami’s fractional-order model for further use in other applications. |
