摘要： A method for producing hydrogen using a feed stream comprising ammonia is provided. The method can include the steps of: heating the feed stream in a first heat exchanger to produce a heated feed stream, wherein the heated feed stream is at a temperature above 500°C; introducing the heated feed stream into a first reaction zone under conditions effective for catalytically cracking the heated feed stream to produce a raw hydrogen stream, wherein the raw hydrogen stream comprises hydrogen and nitrogen; cooling the raw hydrogen stream by indirect heat exchange against a first cooling fluid to form a cooled hydrogen stream; and purifying the raw hydrogen stream to produce a hydrogen product stream and a tail gas, wherein the tail gas has a higher concentration of nitrogen as compared to the hydrogen product stream.

摘要： A method for generating hydrogen is provided. In certain embodiments, the method can include the steps of: introducing a hydrocarbon feed stream, at a first temperature, into a first reaction zone under conditions effective for producing a process stream, wherein the process stream is at a second temperature that is greater than the first temperature; introducing a second feed stream into a second reaction zone under conditions effective for producing a hydrogen product stream, wherein heat needed for producing the hydrogen product stream from the second feed stream is at least partially provided by heat exchange with the process stream; and withdrawing the hydrogen product stream from the second reaction zone.
