IN324557: A process of making impervious palladium membrane over ceramic substrate at near ambient
Abstract
Increasing energy demand needs an alternate source of energy other than fossil fuels. Hydrogen is targeted as the energy source for the next generation due to its environment-friendly applications. However, hydrogen present in lean natural gas, water gas and SMR reaction product has to be separated to get pure hydrogen to be used as fuel. Metallic Palladium/ Palladium alloy tubes of 3 to 5mm thickness are long being used for separating hydrogen from the mixture. Currently, ceramic-supported defect-free Palladium membrane of thickness 2pm to 10pm is the best choice for the preparation of pure hydrogen due to its cost-effectiveness, performance and longevity. In the invention, a non-hazardous, eco-friendly and cheap process of making Palladium membrane is described. Tailor made thickness achieved by this process may also find application in different areas of catalysis.
