A method for producing hydrogen, includes heating a process feed gas stream, flowing the process feed gas stream into a first reaction zone, flowing the intermediate gas stream into a second reaction zone, removing the solid carbon product from the second reaction zone, removing the tail gas stream from the second reaction zone, and removing hydrogen from the tail gas stream. The process gas stream includes methane and steam. The first reaction zone contains a first catalyst, and at least a portion of the process feed gas stream is converted into an intermediate gas stream in the first reaction zone. The second reaction zone contains a second catalyst, and at least a portion of the intermediate gas stream is converted into a tail gas stream and a solid carbon product in the second reaction zone.
