METHOD AND TUBE BUNDLE REACTOR FOR CARRYING OUT ENDOTHERMIC AND EXOTHERMIC GAS PHASE REACTIONS

A METHOD IS PROPOSED FOR CARRYING OUT ENDOTHERMIC OR EXOTHERMIC GAS PHASE REACTIONS BY USING A TUBE BUNDLE REACTOR WITH A TUBE BUNDLE OF CATALYST-FILLED REACTION TUBES, THE METHOD COMPRISING THE FOLLOWING STEPS: A) INTRODUCING A REACTION GAS MIXTURE INTO THE REACTION TUBES;B) DIVIDING-UP OF THE REACTION GAS MIXTURE FLOW FLOWING THROUGH EACH OF THE REACTION TUBES INTO AT LEAST TWO PARTIAL FLOWS, EACH PARTIAL FLOW HAVING THE SAME COMPOSITION; C) FEEDING-IN OF EACH PARTIAL FLOW AT A DIFFERENT POINT ALONG THE CATALYST FILLING WITH AN EXISTING FLOW RESISTANCE; D) DETERMINING THE DESIRED PARTIAL FLOW VOLUME FOR EACH PARTIAL FLOW (V₁, V₂, V₃, V₄ ; E) CALCULATING THE PRESSURE AT THE POINT OF THE FIRST DIVISION OF THE REACTION GAS MIXTURE (9); F) CALCULATING THE PRESSURE IN THE CATALYST FILLING (12) AT THE POINT OF FEEDING-IN OF EACH PARTIAL FLOW (V₁, V₂, V₃, V₄); G) SETTING OF FLOW RESISTANCE FOR EACH POINT OF FEEDING-IN IN SUCH A WAY THAT THE FLOW RESISTANCE AT THE DESIRED PARTIAL FLOW VOLUME CORRESPONDS TO THE PRESSURE DIFFERENCE BETWEEN THE PRESSURES DETERMINED IN STEPS E) AND F). ADDITIONALLY A TUBE BUNDLE REACTOR IS ALSO PROPOSED FOR USE WITH SUCH A METHOD.
