Abstract: A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the hydrocarbon gas and oxygen gas, and then reacting the gases and cooling the products rapidly. The reactor wall is blanketed with a purge gas stream, introduced through a plurality of feed lines. These feed lines deliver purge gas in a vector direction within a 10° angle of the main flow direction of the reactive gas stream. The purge gas is delivered at multiple stages relative to the main flow direction of the reactive gas stream, and the free cross section of the firing space available to the reactive gas stream, at the height of the feed lines of the purge gas stream, is approximately constant.

Abstract: A fixed bed reactor for cyclic, catalytic de-hydrogenation of hydrocarbons, such as alkanes and a reactor-internal device for improving distribution of hydrocarbon feed into the fixed catalyst bed of the reactor. The device comprises a vertical deflector plate with multiple horizontal slits and a frustum cone with multiple perforations on the lateral surface, connected to the bottom end of the plate. The reactor includes a main horizontal reaction vessel containing a fixed catalyst bed and a cactus-shaped inlet assembly sub-divided into three inlets at the upper half portion to supply fluid streams, including hydrocarbon feed, to the catalyst bed. The distributor device is positioned inside a main central vertical arm of the inlet assembly form by the convergene of the three inlets. Various embodiments of the distributor device where the slit thicknesses, distance between slits, perforation diameter, distance between perforations are varied, are also provided.

Abstract: The invention relates to distributing feed vapor more evenly across the interior space of a reactor vessel utilizing a distributor pipe at the inlet end that initially directs the flow of reactants through a flange plate and a series of ring plates. The ring plates are physical spaced such that vapor along the wall of the inlet is mildly obstructed by the flange plate and the ring plates cause the vapor to alter course temper down any diverse velocities that may create hot spots within the catalyst bed. At the end of the distributor pipe is a deflector which directs the feed vapor upwardly and outwardly in the head space of the reactor vessel.

Abstract: The invention provides a process for endothermic gas phase reaction in a reactor, in which reactant gases are introduced into the reactor via a gas inlet apparatus and distributed homogeneously into a heating zone by means of a gas distribution apparatus, wherein the reactant gases are heated in the heating zone to a mean temperature of 500-1500° C. by means of heating elements and then conducted into a reaction zone, the reactant gases reacting in the reaction zone to give a product gas which is conducted out of the reactor via a gas outlet apparatus. Further subject matter of the invention relates to a process for endothermic gas phase reaction in a reactor, wherein the heating of the heating elements is controlled by temperature measurements in the reaction zone, at least two temperature sensors being present in the reaction zone for this purpose, and reactor for performance of the process.
