ABSTRACT:
Apparatus for carrying out catalytic exothermic and endothermic high-pressure gas reactions, comprising a single-walled pressure vessel or shell containing cross-flow (e.g., radial flow) heat transfer exchangers, a continuous catalytic bed having at least two stages, and means for effecting "cross-over" material flows from "outside" to "inside" (for exothermic reactions) and vice versa (for endothermic reactions), whereby conditions of: maximum gas temperature always being in the core of the apparatus, minimal pressure drop, and minimal compression of catalyst particles are achieved, along with significant economic savings in cost of the apparatus and catalyst (through extension of catalyst life).
