Abstract

A method of producing products includes contacting a hydrocarbon gas with a molten media, forming hydrogen and solid carbon based on the contacting, transferring the solid carbon to a heating chamber, heating the solid carbon in the heating chamber, removing at least a portion of the metal disposed on the surface of the solid carbon in the heating chamber, and recovering the solid carbon having at least the portion of the metal removed. The molten media comprises a metal in a molten state, and the carbon comprises the metal disposed on a surface of the solid carbon.
