The preparation of the palladium coatedceramic alumina membrane has been performed using combine sol-gel process andthe electroless plating technique. Ni/γ-Al 2 O 3 catalyst was prepared by the wetnessimpregnation of γ-Al 2 O 3 support. The H 2 O/ C 2 H 5 OH feed molar ratio of the inletreactant was 13:1. The reactions were conducted at various temperatures 400-450°C. The effect of pressures difference across the membrane (2x10 4 -8x10 4 Pa)and flow rate (2.086E-4 – 4.173E-4 mol/s) toward hydrogen yield (%) have beeninvestigated. It is shown in this study that the H 2 O/ C 2 H 5 OH feed molar ratio 2.086E-4mol/s produced a higher hydrogen yield in operating at 450°C and 8x10 4 Pa.References:[1]. H. Bissett, J. Zah and H. M.
