The apparatus for indirectly exchanging heat with narrow channels in a heat exchange type channel reaction zone uses plates containing partially perforated sections to simplify or eliminate the use of manifolds to distribute to and collect different fluids from the various channels. The invention simplifies the operation by directly communicating adjacent channels across sections of perforations located at one end or the other of the channels. The arrangement of this invention provides the advantage of more compact heat exchanging reactor arrangements. In this manner, multiple pass channels can be contained in a single plate channel arrangement using only single or double distribution manifolds at the ends of the channels. The arrangement of the invention can also simplify the use of a single manifold arrangement at one end of the channels to facilitate catalyst unloading and catalyst replacement in the reaction channels. The different channels may provide independent flow paths for different fluids or continuous multi-pass channel flow for a single fluid.

[ What is claimed is:] [1.] A reaction apparatus for contacting reactants with a catalyst in a reaction zone while indirectly heating or cooling the reactants in the reaction zone by indirect heat exchange with a heat exchange fluid, the apparatus comprising:a plurality of spaced apart plates defining a first plurality of channels having a fluid inlet at one end and a second plurality of channels having a fluid outlet at one end;the plurality of spaced apart plates including imperforate plates for blocking fluid flow between adjacent channels with perforated plates alternating with each imperforate plate to define a continuous flow path with the fluid inlet and the fluid outlet at the same end of the first and second plurality of channels: and,at least one section of perforations to communicate fluid between the first and second plurality of channels wherein at least a portion of the spaced apart plates define perforations at one of their ends with each section of perforations extending over only a portion of the plate that defines the perforations, the perforations on the perforated plates alternating from one end of the channels to the other to define independent flow paths through first and second groups of first and second channel pairs and a first manifold at one end of the channels collecting and distributing fluid from the first group and a second manifold at the opposite end of the channels collecting and distributing fluid from the second group of first and second channel pairs.
