Abstract:
1. A tubular reactor for catalytic gas phase reactions comprising, in combination: (a) a heat carrier circulating in a reaction zone around a contact tube bundle inside a reactor jacket, the tube bundle consisting of single piece tubes extending through a first tube plate at the reaction gas inlet side and a second tube plate at the reaction gas outlet side, beginning and ending at the first and second tube plates, respectively, and being sealed with respect to these tube plates, the two tube plates being anchored in an essentially known manner at their edges to the reactor jacket and being sealed with respect to the reactor jacket; (b) gas inlet and gas outlet hoods spanning the face sides of the first and second tube plates, respectively, the first tube plate having a reaction gas side in contact with the reaction gas and a heat carrier side; and (c) a heat insulation zone that borders on the heat carrier side of the first tube plate and that includes at least one of (1) a chamber containing at least one of a solid and liquid heat insulation material and being separated from the reaction zone by a separator plate which is penetrated by the tubes, the tube penetrations allowing for leakages, and (2) built-in components that are stream-calming with respect to the heat carrier.
