Abstract

The palladium membrane is well-known for using in hydrogen separation process. However, the free-standing Pd is expensive and gives low hydrogen flux. The ceramic substrate can be used as a membrane support because it provides many advantages for the palladium membrane, for example, increase mechanical strength and thermal stability, reduce membrane thickness and especially achieve higher hydrogen permeation. In this study, the porous tubular A1 2O3 and YSZ substrate were successfully fabricated from extrusion method. The evolution of density, porosity, flexural strength and microstructure were investigated after sintering at the temperature ranging from 1200 to 1450°C. The effect of sintering temperature was significant when the tubular support was fabricated from the small particle size of YSZ ceramic.
