Research on the Thermodynamics of Benzene in Activated Carbon Regenerated by Spent Catalyst

Abstract:

The adsorption of High volatile harmful Gas benzene onto the of activated carbons regenerated by spent catalyst was studied. The adsorption isotherms of benzene in the activated carbon at temperatures of 20, 30，35°C was measured, and the experimental data were analyzed theoretically by Langmuir isotherm. Avery adsorption heat (△H), free energy (△G) and entropy(△S) of benzene at different adsorption quantity in the activated carbon were calculated. The microstructure of activated carbon to the adsorption of benzene impact of factors was analyzed, the results showed that the regeneration activated carbon had excellent performance capacity of benzene under the same condition the maximum adsorption amount of other properties similar to activated carbon was much higher.
