摘要： The invention relates to a tubular reactor for carrying out catalytic gas-phase reactions, containing a catalyst tube bundle (8) that is traversed by the relevant reaction gas mixture, is filled with a catalyst, extends between two tube sheets (4, 148) and around which flows a heat transfer medium contained within a surrounding reactor jacket (6). The reactor also comprises gas entry and discharge hoods (2; 60) that cover the two tube sheets for supplying the relevant process gas to the catalyst tubes and for discharging the reacted process gas from the catalyst tubes. Together with all the parts that come into contact with the process gas mixture, the reactor is designed to have an appropriate strength for withstanding the deflagration and explosive pressures that are to be taken into account during its operation. The volume available to the process gas mixture prior to its entry into the catalyst tubes is restricted as much as possible in construction and flow engineering terms.

摘要： A cooling system for use in a shell-type reactor includes vertically extending double tubes with an inner tube and an outer tube closed at its lower end. The system also includes a distributor for supplying a fluid cooling medium into the upper end of the inner tubes and a horizontally extending plate, which on its upper surface includes at least two upwardly open, parallel grooves. Two adjacent grooves are separated by a common inner wall. At least one outer tube, having an upper end, is disposed in each groove, through the plate. Each outer tube is tightly welded to the plate on the groove base. The upper, open side of each groove is closed with a lid, so that each groove forms a collector for discharging the cooling medium from the outer tubes. Each inner tube opens through the lid into a distributor and is tightly attached to the lid.

摘要： A tube bundle reactor for carrying out catalytic gas phase reactions, particularly methanation reactions, has a bundle of catalyst-filled reaction tubes through which reaction gas flows and around which heat carrier flows during operation. In the region of the catalyst filling, the reaction tubes run through at least two heat carrier zones which are separated from one another, the first of which heat carrier zones extends over the starting region of the catalyst filling. The reaction tubes each have a first reaction tube portion with a first hydraulic diameter of the catalyst filling and, downstream thereof in flow direction of the reaction gas, at least a second reaction tube portion with a second hydraulic diameter of the catalyst filling that is greater than the first hydraulic diameter of the catalyst filling.
