Abstract: A METHOD IS PROPOSED FOR PROVIDING AN OXYGEN-CONTAINING GAS STREAM FOR THE ENDOTHERMIC REACTION OF AN INITIAL STREAM COMPRISING ONE OR MORE HYDROCARBONS, HAVING A PREDETERMINED OXYGEN CONCENTRATION AND A PREDETERMINED TEMPERATURE, WHEREIN A FLUID FUEL STREAM IS COMBUSTED WITH A PRIMARY AIR STREAM AT ^, VALUES OF THE PRIMARY AIR STREAM TO THE FLUID FUEL STREAM OF FROM 0.6 TO 1.2 TO OBTAIN A COMBUSTION GAS STREAM, AND A SECONDARY AIR STREAM IS ADMIXED TO THE COMBUSTION GAS STREAM TO OBTAIN THE OXYGEN-CONTAINING GAS STREAM FOR THE ENDOTHERMIC REACTION, WITH THE PREDETERMINED OXYGEN CONCENTRATION AND THE PREDETERMINED TEMPERATURE OF THE OXYGEN-CONTAINING GAS STREAM BEING ADJUSTED VIA THE FLOW RATE AND THE TEMPERATURE OF THE SECONDARY AIR STREAM.

Abstract: A REACTOR (1) FOR CARRYING OUT A REACTION BETWEEN TWO FLUID STARTING MATERIALS (2,3) OVER A CATALYST BED (4) WITH PREMIXING OF THE FLUID STARTING MATERIALS (2,3) BEFORE INTRODUCTION INTO THE CATALYST BED WITHIN A DELAY TIME OF LESS THAN 150 MS IN A MIXING-IN DEVICE (5), WHEREIN THE MIXING-IN DEVICE IS MADE UP OF THE FOLLOWING ELEMENTS WHICH ARE ARRANGED ESSENTIALLY TRANSVERSE TO THE INFLOW DIRECTION OF THE FIRST FLUID STARTING MATERIAL STREAM (2): TWO OR THREE ROWS ARRANGED BEHIND ONE ANOTHER OF TUBES (6) WHICH HAVE TURBULENCE GENERATORS ON THE OUTSIDE AND CONSTRICT THE FLOW CROSS SECTION FOR THE FIRST FLUID STARTING MATERIAL STREAM (2) TO FROM 1/2 TO 1/10, WITH THE SECOND FLUID STARTING MATERIAL STREAM (3) BEING PASSED THROUGH THE INTERIORS OF THE TUBES (6) AND INJECTED VIA OPENINGS (7) IN THE TUBES (6) INTO THE FIRST FLUID STARTING MATERIAL STREAM (2); A PERFORATED PLATE UPSTREAM (10) OF THE TUBES (6); AND A PERFORATED PLATE (11) DOWNSTREAM OF THE TUBES (6), IS PROPOSED.

Abstract: A REACTOR (1) FOR CARRYING OUT A CONTINUOUS OXYDEHYDROGENATION OF A FEED GAS STREAM (2) OF SATURATED HYDROCARBONS AFTER PREMIXING WITH AN OXYGEN-COMPRISING GAS STREAM (3) OVER A MOVING CATALYST BED (4) WHICH IS INTRODUCED IN THE LONGITUDINAL DIRECTION OF THEIR REACTOR BETWEEN TWO CONCENTRIC CYLINDRICAL HOLDING DEVICES (5,6) SO AS TO LEAVE A CENTRAL INTERIOR SPACE (7) AND AN INTERMEDIATE SPACE (8) BETWEEN THE MOVING CATALYST BED (4) AND THE INTERIOR WALL OF THE REACTOR TO GIVE A REACTION GAS MIXTURE, WHEREIN THE REACTOR (1) HAS TWO OR MORE REACTOR SECTIONS (9) WHICH ARE SEPARATED FROM ONE ANOTHER BY DISK-SHAPED DEFLECTION PLATES (10) ARRANGED ALTERNATELY IN THE CENTRAL INTERIOR SPACE AND DIVIDED IN SUBREGIONS BY ANNULAR DEFLECTION PLATES (11) ARRANGED IN THE INTERMEDIATE SPACE (8) BETWEEN THE MOVING CATALYST BED (4) AND THE INTERIOR WALL OF THE REACTOR, IN EACH CASE WITH A MIXING-IN DEVICE (12) WHICH IS LOCATED UPSTREAM OF THE MOVING CATALYST BED (4) IN THE FLOW DIRECTION OF THE REACTION GAS MIXTURE AND COMPRISES THE FOLLOWING ELEMENTS: TWO OR THREE ROWS ARRANGED BEHIND ONE ANOTHER OF TUBES (13) WHICH HAVE TURBULENCE GENERATORS ON THEIR OUTSIDE AND CONSTRICT THE FLOW CROSS SECTION FOR THE FEED GAS STREAM TO FROM 1/2 TO 1/10 OF THE FREE FLOW CROSS SECTION, WITH THE OXYGEN-COMPRISING GAS STREAM (3) BEING PASSED THROUGH THE INTERIOR SPACES OF THE TUBES (13) AND BEING INJECTED VIA OPENINGS IN THE TUBES INTO THE FEED GAS STREAM (2), AND A PERFORATED PLATE UPSTREAM OF THE TUBES (13) AND A PERFORATED PLATE DOWNSTREAM OF THE TUBES, IS PROPOSED.
