(54) METHOD AND APPARATUS TO GENERATE A HYDROGEN-RICH PRODUCT


(57) 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.
