A method and composition are disclosed for preventing uncontrolled exothermic reaction in the presence of a catalyst. A catalyst deployed as a finely divided powder which is attached to the surface of a low melting point wax or wax-like material which is utilized as a carrier for the catalyst. During operation should the catalyst overheat due to uncontrolled conditions brought about by a run-away reaction the heat of reaction melts the low melting point wax which would itself wet the surface of the catalyst and prevent further catalysis.
1. A composition capable of gettering hydrogen gas comprising a catalyst composite and a wax or wax-like material wherein said wax or wax-like material have a melting point between about 60.degree. C. and 100.degree. C. and a flash point above about 200.degree. C.; wherein said catalyst composite comprises a catalyst metal dispersed on the surface of an inert porous substrate material, said catalyst metal being selected from the group of elements from the Periodic Table of Elements consisting of New IUPAC Groups 8-10, rhenium, and combinations and alloys...
