The invention belongs to the technical field of hydrogen energy sources and particularly relates to a water-free hydrogen production process. The process integrates multiple procedures including combustion, heat exchange, reforming hydrogen production, water-vapor conversion, carbon monoxide purification, gas-liquid separation, liquid collection and the like. Energy and products of combustion reaction in a system are taken into comprehensive consideration and subjected to coupling matching with energy and materials required by hydrogen production reaction, and water collection is considered while energy efficiency of the whole process is guaranteed through design and matching of multiple heat exchangers and heat exchange between raw material flow and reactant flow; the water-free hydrogenproduction process is implemented without external water supply. Before exhausting of combustion tail gas, environmental friendliness of the process is well guaranteed by a catalytic reaction and physical adsorption combined comprehensive treatment method. Final product gases mainly include hydrogen, nitrogen, carbon dioxide and carbon monoxide, and the carbon monoxide concentration can be controlled below 10ppm.
