Study on CO₂ Absorption Enhancement by Adding Active Carbon Particles into MEA Solution

Abstract

The chemical absorption of CO₂ is generally recognized as the most efficient post-combustion technology of CO₂ separation at present. A study on CO₂ absorption enhancement by adding small particles of active carbon into MEA solution is investigated within a self-designed glass stirring tank. Experiments of different particle loadings and different particle sizes have been conducted. When active carbon particle concentration is fewer, compared to the absorption rate of CO₂ gas absorbed by MEA aqueous solution, the role of active carbon adsorption CO₂ gas is negligible. The enhancement efficiency of CO₂ absorption could be improved by 10% to the upmost in this liquid-particle system.
