Disclosed are a fixed-bed, catalytic reactor wherein reaction heat can be exchanged against a heat exchange medium circulating indirectly through the catalyst bed, and a catalytic process comprising operation of the reactor. The reactor comprises a catalyst bed having internally embedded banks of heat exchange tubes. An inlet distributor distributes reactants for flow through the bed. The distributed fluid passes through the bed in a flow path wherein a catalytic reaction occurs. The reaction effluent is then collected from the bed by an outlet product collector. A heat exchange medium circulated through the internal heat exchange tubes adds or removes reaction heat as required for enhanced conversion in the reactor. Multiple heat exchange tubes can be used, and inlet and discharge manifolds are provided for distributing the circulating heat exchange medium. The heat exchange tubes can be spaced in accordance with the heat interchange required to optimize the reaction rate. |
