Abstract:
1. A reformed gas production apparatus comprising: a reaction chamber containing a reforming catalyst; a supply route connected to a fuel source that contains a plurality of types of hydrocarbons and configured to supply a fluid that includes a fuel containing a hydrocarbon having at least two carbon atoms, at least one of steam and a carbon dioxide-containing gas, and an oxygen-containing gas, to the reaction chamber; a reformed gas conduction route configured to conduct a reformed gas that is produced through a reforming reaction and that includes methane, hydrogen, and carbon monoxide, from the reaction chamber; and reaction chamber temperature control means programmed to control a temperature of the reaction chamber; wherein the fuel is a mixed fuel that contains a plurality of types of hydrocarbons each having at least two carbon atoms; and wherein the reaction chamber temperature control means is programmed to regard the thermal decomposition index temperature of the fuel, which is a value of the lowest thermal decomposition temperature of the plurality of types of hydrocarbons that make up the fuel, the thermal decomposition temperature being determined based on a gas type and a concentration of hydrocarbons having at least two carbon atoms that make up the fuel, as an upper limit temperature of the reforming reaction region, and in a case where the maximum temperature in the reforming reaction region exceeds the upper limit temperature, the reaction chamber temperature control means performs control to cool the reaction chamber.
