ガス変成装置によって達成される。According to the present invention, air and a hydrocarbon gas such as butane are supplied and mixed in a retort filled with a catalyst and maintained at a high temperature to convert an endothermic gas. The retort is a cylindrical Laval tubular shape having a constricted part in the center, and is disposed in a heating furnace, and an air preheating chamber is formed inside the retort with the constricted part as a boundary. A mesoche-like diaphragm separates the catalyst-filled section filled with catalyst from the retort, and the end of the retort on the air preheating chamber side is connected to the air preheating chamber through a flow needle that measures and controls the amount of air supplied from the air supply source. A feeding air supply pipe is connected to the retort catalyst filling chamber, and an air insulating material having a cooling structure provided on the furnace wall of the heating furnace is disposed on the constriction portion side of the retort catalyst filling chamber, and Through a flow meter that measures and controls the amount of hydrocarbon gas such as butane supplied, multiple butane and other hydrocarbon gas supply pipes are connected from multiple directions guided by piping outside the furnace, and then the retort is filled with catalyst.
