A method of preheating a feed to a molten material reactor comprises heating a hydrocarbon feed in a first heat exchanger using a cooled product gas to produce a heated hydrocarbon feed stream, pyrolyzing at least a portion of the C.sub.2+ hydrocarbons in the heated feed stream in a pyrolysis reactor to produce a pyrolyzed hydrocarbon stream, and heating the pyrolyzed hydrocarbon stream in a second heat exchanger using a product gas to produce a pre-heated feed gas. The heated hydrocarbon feed stream comprises methane and one or more C.sub.2+ hydrocarbons.

A method for thermal cracking of a hydrocarbon to produce hydrogen gas and carbon comprises heating a molten medium to an operating temperature sufficient to thermally crack the hydrocarbon. The operating temperature may, for example be in the range of 600° C. to 1100° C. The method mixes the hydrocarbon into the heated molten medium and pumping the mixed molten medium and hydrocarbon through a reactor. In the reactor, the hydrocarbon undergoes a thermal cracking reaction which forms hydrogen gas and carbon black. The method separates the carbon and hydrogen gas from the molten medium that has passed through the reactor. In some embodiments, the flow of the molten medium in the reactor is a turbulent flow.
