CO2 Adsorption By Various Catalysts

Abstract

Global warming arising from the emission of greenhouse gases, especially CO₂, has become a biggest issue all over the world in the recent years. Though various CO₂ capture technologies have been proposed, chemical absorption and adsorption are currently believed to be the most suitable ones for post-combustion power plants. In this review paper, we will discuss different physical adsorbents; various mesoporous solid adsorbents impregnated with polyamines and grafted with amines are reviewed. The major concern is for CO₂ adsorption capacity at different temperature and pressure are compared and discussed. More effective and less energy-consuming regeneration techniques for CO₂-loaded adsorbents are also proposed.
