Dense Pd/SS-316L composite membranes were prepared using conventional electroless plating and a new synthesis procedure based on electroless plating with osmosis. Membranes from the new synthesis technique have about five times higher hydrogen permeation rate and exhibit better thermal stability. Ethane dehydrogenation reaction was conducted in a packed bed membrane reactor (PBMR) with Pd/SS-316L membrane and Pt-Sn/alumina catalyst pellets. Supra-equilibrium conversions were obtained with a better than 95% selectivity towards ethylene. The effect of non-uniform distribution of catalyst in pellets was also investigated.
