A composition suitable for safely removing hydrogen from gaseous mixtures containing hydrogen and oxygen, particularly those mixtures wherein the hydrogen concentration is within the explosive range. The composition comprises a hydrogenation catalyst, preferably Pd dispersed on carbon, wherein the concentration of Pd is from about 1-10 wt %, dispersed in a polymeric material matrix. As well as serving as a matrix to contain the hydrogenation catalyst, the polymeric material, which is substantially unreactive to hydrogen, provides both a diffusion restric...


[ I claim:] [1.] A method for making a powdered catalyst mixture comprising the steps of:a) mixing a hydrogenation catalyst with an uncured, liquid silicone rubber;b) curing said liquid silicone rubber to form a silconized hydrogenation catalyst;c) mixing the siliconized hydrogenation catalyst with a second polymer material, selected from the list consisting of styrene/butadiene rubber, styrene/butadiene/acrylonitrile rubber, and polybutadiene rubber, by comminuting said silconized catalyst and said second polymer material together with a liquid grinding...
