Abstract
Abstract The invention provides an apparatus for carrying out chemical reactions, in the presence of at least one catalyst, in at least one reaction zone equipped with heat exchanger plates which make it possible to control the temperature of the zone. The apparatus mainly comprises a reactor, at least one central distributor manifold, a plurality of distributor manifolds, at least one central receiver manifold, a plurality of receiver manifolds and a plurality of continuous and elongate hollow plates, preferably substantially perpendicular. The hollow plates can contain adjacent channels having one of the following shapes: square, rectangular, triangular, sinusoidal.
