ABSTRACT:
A method for carrying out endothermic or exothermic gas phase reactions by using a tube bundle reactor with a tube bundle of catalyst-filled reaction tubes comprises 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); andg) 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).
