Abstract:
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.
