摘要： Process for heterogeneously catalyzed partial dehydrogenation of a hydrocarbon, comprises conducting a reaction gas mixture input stream comprising hydrocarbons, with molecular oxygen and molecular hydrogen through a fixed catalyst bed; filling inert shaped bodies and then catalyst shaped body in the flow direction of input stream; conditioning the input stream with an activation energy in its inlet area for the combustion reaction of molecular hydrogen with molecular oxygen; and dehydrogenating at least a partial quantity of hydrocarbon. Process for heterogeneously catalyzed partial dehydrogenation of a hydrocarbon, comprises conducting a reaction gas mixture input stream comprising a hydrocarbon to be dehydrogenated, with molecular oxygen and molecular hydrogen through a fixed catalyst bed, which is disposed in a shaft with predetermined cross section; filling inert shaped bodies and then catalyst shaped body in the flow direction of input stream; conditioning the input stream with an activation energy in its inlet area for the combustion reaction of molecular hydrogen with molecular oxygen to water and/or combustion reaction of hydrocarbon with molecular oxygen to carbon monoxide and water; dehydrogenating at least a partial quantity of hydrocarbon, by which the reaction gas mixture input stream is generated inside the shaft; dosing the molecular hydrogen with a volume flow (V1) and an input stream (I) containing at least one dehydrating hydrocarbon on the fixed catalyst bed, before the catalyst bed is dosed with input stream (II) containing molecular oxygen with a total volume flow (V2), where the input stream (II) is dosed in large number through outlet openings (A) present in the flow direction of the input stream (I), in such a manner that, (a) the direction of the majority (M) of input stream (II) from all the outlet openings (in the absence of input stream (I)) exhibits an angle of 90+-60[deg]; (b) the distance (D) of the majority of all outlet openings from the fixed catalyst bed, in relation to the flow speed (W) of the input stream (I) in the shaft, is = the induction time (J) of the reaction gas input mixture multiplied with 2.W; (c) by a projection of the focal points of a majority of all outlet openings in the flow stream direction of the input gas stream (I) in the projection level vertical to the flow stream direction of the input gas stream (I), within the projection level for at least 75% of the projection surfaces, which are held by the input gas stream (I), the number (ZA) amounts to >= 10 in any considered surface m 2> in which one finds outlet opening focal points; (d) the number (ZA) amounts to focal points of the outlet opening, from which the number of emerging individual input stream (II) does not deviate by more than 50% of its average; (e) within the number (ZA) of all outlet openings, a distance (D) between one outlet opening focal point and the next outlet opening focal point, is not more than the equation 2.(lm 2>/ZA) 1> > 2>; and (f) the ratio of V1:V2 amounts to >= 8.

摘要： The invention relates to a reactor for partial oxidation of a fluid reaction mixture in the presence of a heterogeneous particulate catalyst. Said reactor comprises one or several cuboid heat-transfer sheet modules (1) which are each composed of two or several right-angled heat-transfer sheets (2), arranged parallel to each other such as to form a slit (3) which can be filled with the heterogeneous particulate catalyst and through which the fluid reaction mixture flows, the heat of reaction being absorbed by a heat carrier which flows through the heat-transfer sheets (2) and at least partially evaporates. Said reactor also comprises a mainly cylindrical envelope (4, 15, 16) which depressurizes the heat-transfer sheet modules and fully surrounds said modules, said envelope being composed of a cylinder casing (4) and of caps (15, 16), closing said casing at both ends, the longitudinal axis of which extends parallel to the plane of said heat-transfer sheets (2). Said reactor finally comprises one or several sealing elements (7, 23), arranged so that the fluid reaction mixture flows only through the slit (3), except through the reactor interior spaces, defined by the caps (15, 16).
