ABSTRACT:
Hydrogen is produced by the combustion of carbon with air to produce a combustion gas effluent containing carbon dioxide and nitrogen. The carbon dioxide is separated and reacted with carbon to produce carbon monoxide. The resulting produced carbon monoxide is then reacted with steam to produce carbon dioxide and hydrogen and the resulting produced hydrogen separated. The carbon utilized for the production of hydrogen may be obtained by the thermal decomposition of hydrocarbons to yield carbon and gaseous hydrogen or the carbon utilized in this process may be obtained from a solid carbonaceous fuel, such as coal or coke or the like. A reactor useful for the thermal decomposition of a hydrocarbonaceous fuel to produce gaseous hydrogen and carbon and particularly adaptable for use in the process in accordance with this invention comprises a reactor provided with a high temperature thermal decomposition zone and means therein for effecting the separation between any solid ash constituents of the fuel, the resulting produced carbon and the resulting produced gaseous hydrogen.
