Abstract

The compact steam reformer of the present invention integrally comprises a housing; a reforming reactor having an upper mixing compartment for mixing natural gas and steam and a lower compartment for accommodating a catalyst bed; a natural gas feeding coiled pipe through which natural gas is introduced while being heated; a steam generating coiled pipe in which pure water is converted to steam by the exhaust; a metal fiber burner for heating the reforming reactor; a high-temperature converter for primarily removing carbon monoxide from a synthetic gas; a low-temperature converter for secondarily reducing the carbon monoxide level of the synthetic gas; and a heat exchanger, provided between the high-temperature converter and the low-temperature converter, for cooling the gas effluent from the high-temperature converter.
