A process and apparatus cools a heat exchange type reaction zone by passing the incoming reactants through heat exchange channels in heat exchange relationship with the reaction zone. The invention simplifies the operation and construction of the heat exchanging type reaction zone by directly communicating reaction channels that contain the reaction with the heating channels that heat reactant across an open manifold located at the end of the channels. Additional reactants, cooling fluids, or other diluents may enter the process directly through the manifold space to permit further temperature control of the reaction zone. The invention promotes better heat transfer efficiency than tube and shell heat transfer arrangements that have been used for similar purposes. The narrow channels are preferably defined by corrugated plates. The reaction channels will contain a catalyst for the promotion of the primary reaction.

[ What is claimed is:] [1.]1. A process for contacting reactants with a catalyst in a reaction zone while indirectly heating the reactants and cooling the reaction zone by indirect heat exchange, the process comprising:a) passing a reactant-containing stream through a plurality of narrow heated channels defined by at least a first portion of spaced apart plates to heat the reactant-containing stream and to produce a heated reactant stream, at least a portion of the heated channels containing a catalyst for the promotion of an endothermic reaction;b) passing the heated reactant stream as a reaction stream to a reaction zone and contacting the reaction stream with a catalyst material for the promotion of an exothermic reaction in the reaction zone to produce a reacted stream;c) indirectly heating the reactant-containing stream in the heated channels by indirect heat exchange with the reaction stream or the reacted stream across the spaced apart plates;d) communicating common ends of at least two channels defined by the spaced apart plates in a common manifold; and,e) collecting at least a portion of the reacted stream downstream of channels defined by a second portion of the spaced apart plates.
