ABSTRACT:
A hydrocarbon getter pump for use in sealed envelopes comprises an active metal alloy capable of gettering hydrogen, a nickel catalyst and means for heating the nickel catalyst and getter material from 300.degree. to 500.degree. centigrade. The heated catalyst dissociates the hydrocarbon into hydrogen and carbon. The getter material getters the hydrogen and the carbon is deposited on the surfaces of the catalyst.
