Adsorption Thermodynamics Study on CCl2F2 over Solid Base Na2O/ZrO2

Catalytic hydrolysis decomposition of dichlorodifluoromethane (CCl2F2) in the presence of water vapor and oxygen was studied over solid base Na2O/ZrO2 using a fixed-bed reactor. The CCl2F2 adsorption was multilayer chemical adsorption and its process was corresponding with Freundlich model. Its adsorption heat was from 43.74 to 76.31 KJ.mol-1, and the CCl2F2 adsorption over solid base Na2O/ZrO2 was exothermic and chemical.
