Abstract:
1. Reactor device for carrying out chemical reactions requiring heat exchange, said reactor, which is elongate along an axis, having, at a first end, at least one means for supplying at least on reactant and, at an opposite end, at least one means for evacuating the effluents formed, and having a plurality of heat exchange means separated by at least one internal partition participating in controlling the residence time of the reactant or reactants and increasing the heat exchange surface inside the reactor, and passages for circulating the reactant or reactants and/or effluents, provided between said heat exchange means and said internal partitions, characterized in that the reactor has at least one enclosure made of a refractory material ensuring heat insulation and containing the heat exchange means and the internal partitions, in that said enclosure is contained in an envelope containing the reactant or reactants and/or effluents circulating inside said reactor, in that the enclosure is fitted to the containment envelope in such a way as to prevent gas bypasses between the outside of said enclosure and the inside of said envelope, and in that the containment envelope is provided within an outer shell whose cross section is substantially circular and whose inside diameter is substantially equal to the largest dimension of the outside diagonal of the containment envelope.
