Abstract

• Nowadays, carbon dioxide is produced extensively by using many industrial processes and domestic processes. The greatest physiological effect of carbon dioxide is to stimulate the respiratory center, able to cause dilation and constriction of blood vessels and formed the environmental impact. In this paper, composite carbon-zeolite sorbent was prepared and utilized to study the adsorption of carbon dioxide. The adsorption of carbon dioxide on carbon-zeolite composite was measured by using volumetric method. The adsorption capacity was studied by using Langmuir equation, Freundlich equation and Temkin equation. The comparison of these results with that of zeolite molecular sieve was also presented. It was observed that very high carbon dioxide uptake was observed with composite during gas adsorption studies.
