    摘要: A catalytic process and apparatus therefor for the manufacture of hydrogen cyanide. In the process an oxygen rich oxidant stream and at least one oxidant-free feed stream containing methane and ammonia are separately preheated and rapidly mixed to form a detonable mixed stream at a temperature which is at least 50null C. below the autoignition temperature of the mixed stream. The mixed stream is then conveyed to a catalyst capable of catalysing the formation of hydrogen cyanide at such a velocity that detonation is avoided. The process is more energy efficient and gives rise to an effluent stream containing more hydrogen than the conventional Andrussow process.

    摘要: Processes for carrying out catalytic exothermic and endothermic high-pressure gas reactions with 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 said vessel or shell, minimal pressure drop, and minimal compression of catalyst particles are achieved, along with significant economic savings in cost of the pressure vessel or shell and catalyst (through extension of catalyst life).
