Reactor and method for producing same

A reactor comprising a reactor vessel and, inside of the reactor vessel comprises:

• a plate assembly which is mounted in suspended form and which is formed by a plurality of cooling plates through which a cooling fluid can flow, wherein between the cooling plates intermediate spaces, in which a catalyst is arranged, are formed such that a reaction gas can flow through the intermediate spaces and come into contact with the catalyst,
• a distributor which is attached to the plate assembly on an underside of the plate assembly,
• at least one supply line, via which the distributor is connected to a respective cooling fluid inlet of the reactor vessel,
• a collector which is attached to the plate assembly on a top side of the plate assembly,
• at least one discharge line, via which the collector is connected to a respective cooling fluid outlet of the reactor vessel,
• wherein flow paths for the cooling fluid are formed, the flow paths in each case leading from one of the cooling fluid inlets through the corresponding supply line, the distributor, one of the cooling plates, the collector and one of the discharge lines to the corresponding cooling fluid outlet, and wherein the at least one supply line is curved in such a manner that, when viewed in a projection onto a plane containing the axis of the reactor vessel, an orientation of the supply line in a first portion of the supply line changes over the course of the supply line by at least 135°, and in a second portion of the supply line, which adjoins the first portion in the direction of the distributor, an orientation of the supply line changes over the course of the supply line by at least 45°, and wherein the at least one supply line is curved in the first portion in the opposite direction to the second portion.
