Abstract
An apparatus for producing hydrogen in a steam methane reformer with reduced carbon emissions, the apparatus comprising: a first heat exchanger configured to heat a feed stream comprising methane to produce a heated feed stream that is at a temperature above 500° C.; a reaction zone in fluid communication with the first heat exchanger, wherein the reaction zone is configured to receive the heated feed stream under conditions effective for catalytically cracking the heated feed stream and catalytically crack the heated feed stream to produce a reformed stream, wherein the reformed stream comprises hydrogen, carbon monoxide, and unreacted methane; a shift conversion unit in fluid communication with the reaction zone, wherein the shift conversion unit is configured to receive the reformed stream in the presence of steam and produce a shifted gas stream comprising hydrogen and carbon dioxide; and a hydrogen purification unit configured to receive the shifted gas stream and purify the shifted gas stream to produce a hydrogen product stream and a tail gas; wherein the conditions effective for catalytically cracking the heated feed stream comprise providing heat to the reaction zone via combustion of a fuel and a hydrogen fuel stream in presence of an oxidizer, wherein the fuel comprises ammonia, wherein a flue gas is produced by the combustion of the fuel and the hydrogen fuel stream.
