Process Simulation of Dry Impregnation for preparing Supported Catalyst

For the method of dry impregnation, an imbibition-adsorption model is proposed and its numerical solution has been obtained. From both theoretical and experimental results, it can be concluded that the relative adsorption coefficient, adsorption equilibrium cosntant, wetting angle and impregnating time may profoundly affect the distribution of catalyst active species in its support.
