Since the reaction is an endothermic reaction,
It is necessary to heat the reformer containing the catalyst for the reforming reaction. At the time of startup, this heating is usually performed with a hydrocarbon-based high-calorie fuel such as LPG or city gas (hereinafter referred to as fuel gas).
