Combinatorial Search for Hydrogen Separation Membranes 

 

Industrial production of hydrogen from syngas, generated from steam reformation of natural gas or coal, sets conditions for hydrogen separation membranes in terms of operating conditions. An alternative source for hydrogen is a syngas generated by gasification of municipal solid wastes which are likely to set more stringent conditions for the separation membranes. There is, therefore, a growing demand for separation membranes with improved permeability and particularly of low cost.

 

Among various alternatives, metal membranes are particularly attractive due to their high selectivity for hydrogen. Traditional approach of synthesizing one membrane composition at a time and testing it for permeability is not always successful. Therefore, a method that would allow the synthesis of multiple material compositions and which may then be evaluated by a rapid screening technique is a highly useful approach to identify the material composition best suited for the purpose.

 

The present work is a part of comprehensive program initiated on hydrogen separation membranes produced via vacuum deposition techniques. Membranes in question are either self-supporting films of several microns in thickness or in the form of thin films deposited on a support material, normally a stainless steel filter. More than 20 compositions were deposited in a single experiment where the substrates formed an array suitable positioned over the sputter sources in a triangular geometry. Filters were screened using a permeability tester which when needed, can be adapted for rapid testing. The use of this method is illustrated in Pd-Nb-Ti ternary system.
