Abstract
Reactor comprises (a) an injector complete with a divergent diffuser; (b) a catalyst cage with centrifugal radial flow and an internal cavity of cylindrical shape, one end of which is situated directly downstream of the end part of the diffuser; (c) an external shell which is coaxial with the injector and the catalyst cage, and transfers at least part of the gases coming from the catalyst cage, to the injector, and (d) a heat exchanger, in which at least part of the gases recycled in the process and coming from the catalyst cage exchanges heat indirectly with another fluid.
