Abstract
An improved reactor is disclosed wherein a high temperature product gas discharged from a catalyst bed within the reactor is cooled in a central heat exchanger installed within the reactor by heat exchange with a low temperature feed gas comprising gaseous raw materials for the reaction, and the product gas is thereafter flowed along the inner surface of an outer pressure vessel in order to maintain the outer pressure vessel at a low temperature. Inlet and outlet pipes for a coolant which coolant is circulated through a coolant passage structure which penetrates the catalyst bed in order to absorb the heat of reaction, both penetrate the top cover of the outer pressure vessel so that the coolant passage structure can be readily removed for maintenance and inspection, and the overall design of the reactor is simplified.
