ABSTRACT:
A catalytic reaction apparatus includes a catalytic reaction vessel containing a catalyst for an exothermic reaction. First and second catalyst regions contain a catalyst and have different catalytic performances from one another. At least two raw materials are introduced in the catalytic reaction vessel and passed through the first and second catalyst regions to react to generate heat. The heat is transferred to a heat medium arranged outside and contacting the catalytic reaction vessel so that distribution of temperature is controlled in the catalytic reaction vessel. The difference in catalytic performance is achieved by controlling concentration of the catalyst or by using different catalyst species.
