Abstract

In this study, the potential of utilizing the porous alumina ceramic membrane coated with palladium as a hydrogen permselective membrane has been studied. The ceramic membrane is characterized by high permeability but at low hydrogen selectivity. In order to increase the pure hydrogen selectivity and to obtain high hydrogen yield on the ceramic membrane, palladium was coated on the alumina membrane surface. Such an arrangement would also enable the ceramic membrane to be operated at higher temperature. The preparation of the palladium coated ceramic membrane was carried out using combine sol-gel process and the electroless plating technique. The effect of combine sol-gel process with electroless plating towards hydrogen permeation and hydrogen permselectivity were analysed. The thickness of the a-Alumina and Palladium composite membranes were analysed using a Scanning Electron Microscopy (SEM). The resulting membrane showed significantly higher hydrogen permeation but the same time decrease hydrogen permeability and permselectivity.
