Abstract:
To provide a process for partial-oxidation of a reactant gas into hydrogen and carbon monoxide, which is able to achieve complete conversion of the reactant within a short period of time by pre-heating the reactant through a heat-exchanger and converting the reactant into the hydrogen and carbon monoxide using an electrically-heating type catalyst. In the process, a reactant gas is allowed to pass through a reactor that has a heat-exchanger and is packed with an electrically-heating type catalyst and a noble-metal wash-coated metal-monolith catalyst to be converted into hydrogen and carbon monoxide. The reactant gas is a mixture gas containing methane, natural gas, liquid propane gas, naphtha, gasoline, and a gas containing hydrocarbon and oxygen of diesel oil. The reactant gas is pre-heated by a high-temperature reaction-generation gas in the heat-exchanger and then injected into the reactor.
