Adsorption of carbon dioxide in zeolite LiZSM-5.

Carbon dioxide is a strategic gas in many industrial processes. Large amounts of carbon dioxide are emitted into the atmosphere leading to global environmental problems. It is a product of combustion and a greenhouse gas; capturing it for reuse is a major problem facing our society today. One way to recover carbon dioxide is to use an adsorption process. Zeolites are a potential material for the selective adsorption and separation of carbon dioxide. Zeolites are of great interest because of their ability to change their properties, both textural and chemical, which ultimately affect the adsorption properties of zeolites. This paper presents the results of a study of isotherms and basic thermodynamic characteristics of carbon dioxide adsorption on zeolites like ZSM-5. The adsorption isotherm is also described by the equations of the theory of volume filling of micropores (VMOT). [ABSTRACT FROM AUTHOR]
