Abstract: A catalyst system, which is active in pyrolyzing methane at reaction temperatures above 700° C., comprising a molten salt selected from the group consisting of the halides of alkali metals; the halides of alkaline earth metals; the halides of zinc, copper, manganese, cadmium, tin and iron; and mixtures thereof, the molten salt having dispersed therein one or more catalytically active forms of iron, molybdenum, manganese, nickel, cobalt, zinc, titanium, and copper in the form of finely divided elemental metals, metal oxides, metal carbides or mixtures thereof.

Abstract: A reactor system, which is active in pyrolyzing methane at effective conditions, comprising a molten salt medium and a reaction vessel, the molten salt being contained within the reaction vessel using various methods of catalyst distribution within the vessel such that when methane passes through the vessel, it comes into contact with said catalyst causing a pyrolysis reaction thereby producing molecular hydrogen with reduced carbon dioxide emissions. The catalyst may be placed within the reaction vessel either as suspended particles or in a structured packed form.
