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.

摘要： With a method for operating a tube bundle reactor for exothermic gas phase reactions having a tube bundle with catalyst-filled reaction tubes (2), wherein the one ends of the reaction tubes are spanned by a gas inlet hood and the other ends are spanned by a gas outlet hood and wherein around the outside of the reaction tubes a heat transfer medium flows to carry off reaction heat. An explosive gas mixture (G) is introduced into the reaction tubes (2) via the gas inlet hood and after reaction the gas mixture (G), that may still be explosive, it is led off from the reaction tubes via the gas outlet hood. A limit temperature in the reaction tubes (2) is specified that lies above the normal operating temperatures in the reaction tubes (2) but at most equals the ignition temperature of the explosive gas mixture (G) Each non-operating high temperature region (7) forming in the reaction tubes (2) whose temperature is at least equal to the limit temperature and which migrates in the respective reaction tube (2) in the longitudinal direction thereof is stopped while still in the reaction tube (2) so that the high temperature region (7) is prevented from advancing into the gas inlet hood or the gas outlet hood.
