International Journal of Environment and Waste Management (IJEWM), Vol. 22, No. 1/2/3/4, 2018

Abstract: The rising concern over global climate change has geared up a desire for reduction in greenhouse gas emissions. In this work, a systematic review of the literature work done so far on the application of adsorption and hydrate-based gas separation for the capture of CO₂ from both fuel gas and flue gas mixtures has been carried out. Different adsorbents and operating conditions have been studied. Improvements in the adsorption capacities by thermal, mechanical and chemical activation have also been analysed. A range of reactor designs and the role of thermodynamic and kinetic promoters in the hydrate-based gas separation process for CO₂ capture have been reviewed. Each experimental work has been scrutinised independently and compared finally. Furthermore, the advantages and limitations of adsorption process and hydrate-based gas separation process have been pointed out.
