The method of fixed bed breakthrough curves has been applied to develop the dynamic adsorption model that describes the characteristics of carbon monoxide,carbon dioxide and methane on compound adsorbents with rare earth elements.The numerical solutions of parameters on adsorption kinetics were obtained by the method of orthogonal collocation. The method of fixed bed breakthrough curves is a very useful experimental medium.It can provide the means of adsorption characteristics of other systems. Those data were essentially required for the design of the adsorption separation process.
