Abstract
A control apparatus can maintain a substantially constant temperature of a reforming reaction in which a partial oxidation reaction occurs. The control apparatus can be used for a reformer that reforms reformats fuel into fuel by an endothermic reforming reaction and a partial oxidation reforming reaction. The amount of oxygen supplied for the partial oxidation reaction is determined based on an amount of the raw material and on theoretical endothermic values and exothermic values of the respective reforming reaction and partial oxidation reaction.

A control apparatus for a reformer, comprising:
- a controller that:
- controls introduction of raw material and oxygen into the reformer so as to promote an endothermic reforming reaction and an exothermic partial oxidation reaction in the reformer;
- determines an amount of oxygen supplied for the partial oxidation reaction based on an amount of the raw material and on theoretical endothermic and exothermic values for the reforming reaction and the partial oxidation reaction, respectively;
- determines a length of time from the introduction of the raw material to occurrence of the reforming reaction and the partial oxidation reaction;
- and
- adjusts the determined amount of oxygen supplied based on the determined length of time.
