To enable stable recovery of hydrogen and carbon monoxide with high efficiency in the method of gasifying organic waste and to thereby enhance the applicability to an electricity generation system for a fuel cell.
In the gas conversion apparatus for forming a gas having hydrogen and carbon monoxide as the major components by supplying organic waste 10, an oxidizing agent 13, and a combustion improver 15 to a gas converter 1 to partially burn the organic waste 13, a temperature sensor 17 for detecting the temperature of the inside of the converter, a gas analyzer 19 for analyzing a formed gas 5, and an arithmetic unit 20 for calculating the amount of oxygen necessary to render the concentration of hydrogen and/or carbon monoxide in the formed gas 5 around a maximum based on the result of the analysis by the gas analyzer 19 are provided. A control unit 18 controls the feed amount of the combustion improver 15 so as to render the temperature of the inside of the converter 1,200-1,500°C, preferably 1,300-1,400°C based on the signal of the temperature sensor 17 and also controls the feed amount of the oxidizing agent 13 so as to feed the amount of oxygen necessary to render the concentration of hydrogen and/or carbon monoxide around a maximum based on the data from the arithmetic unit 20.
