    Abstract: There is provided a hydrogen generator that prevents supply of droplets to a reforming catalyst layer and that exhibits stable performance.The hydrogen generator includes a water evaporation unit 7 to which a raw gas and water is supplied; a reforming catalyst layer 9 to which a gas mixture is supplied from the water evaporation unit 7; a burner 4 configured to mix and combust a fuel gas with air; a combustion exhaust gas flow channel 16 which is provided on an inner side of the water evaporation unit 7 and through which the combustion exhaust gas flows; and a conversion catalyst layer 10 which is disposed on an outer side of the water evaporation unit 7 and to which a reformed gas is supplied. The water evaporation unit 7 includes double cylinders 100 and 101 and a helical round bar 18 sandwiched between the cylinders 100 and 101, and a pitch of the helical round bar 18 in a downstream portion of the water evaporation unit 7 is made smaller than a pitch of the helical round bar 18 in a portion of the water evaporation unit 7 except the downstream portion thereof.

    Abstract: An ammonia converter is disclosed. The converter can alter the conversion of ammonia by controlling the reaction temperature of the exothermic reaction along the length of the reactor to parallel the equilibrium curve for the desired product. The converter can comprise a shell 101 and internal catalyst tubes 109. The feed gas stream enters the reactor, flows through the shell 101, and is heated by indirect heat exchange with the catalyst tubes 109. The catalyst tubes 109 comprise reactive zones 122 having catalyst and reaction limited zones 124 that can comprise inert devices that function to both separate the reactive zones, increase heat transfer area, and reduce the temperature of the reaction mixture as the effluent passes through the catalyst tube 109.
