Abstract: A method for the partial gas-phase oxidation of C3 and/or C4 precursor compounds to give (meth)acrolein and/or (meth)acrylic acid in the presence of a heterogeneous particulate catalyst in a reactor is disclosed, having several parallelepiped heat-transfer plate modules (1), each comprising two or more rectangular parallel heat-transfer sheets (2), arranged to leave a gap (3) therebetween which may be filled with the heterogeneous particulate catalyst and through which the fluid reaction mixture flows, whereby the heat of reaction is removed by a heat transfer agent, flowing through the heat transfer plates (2), which is thus partly evaporated and a predominantly cylindrical shell (4, 15, 16), completely enclosing the heat transfer plate module and relieving the pressure thereon which has itself a cylindrical sleeve (4) and caps (15, 16) sealing the ends thereof, the longitudinal axis of which is arranged parallel to the plane of the heat-transfer plates (2) and one or more sealing elements (7, 23), arranged such that the fluid reaction mixture only flows through the gaps (3) when not flowing in the reactor inner chamber as defined by the caps (15, 16).

Abstract: Preparation of chlorine involves passing hydrogen chloride and gas stream comprising molecular oxygen in a reactor (1) having parallel catalyst tubes (2) charged with fixed-bed catalyst and at least one deflector plate (6) perpendicular to the reactor. The plates leave passages on opposite sides of the reactor free next to its interior wall. A liquid heat transfer medium circulates between tubes.

Abstract: A process for preparing chlorine by gas-phase oxidation of hydrogen chloride by means of a gas stream comprising molecular oxygen in the presence of a fixed-bed catalyst, wherein the process is carried out in a reactor ( 1 ) having heat-exchange plates ( 2 ) which are arranged in the longitudinal direction of the reactor ( 1 ) and have a spacing between them and through which a heat transfer medium flows, inlet and outlet facilities ( 3, 4 ) for the heat transfer medium to the heat-exchange plates ( 2 ) and also gaps ( 5 ) between the heat-exchange plates ( 2 ) in which the fixed-bed catalyst is present and into which the hydrogen chloride and the gas stream comprising molecular oxygen are passed, is described.

Abstract: A gas phase oxidation reactor has one or more endothermic or exothermic stages that take place in the presence of a heterogenic particle catalyst. The catalyst comprises one or more stacked perforated panel(s) (1) with a coefficient of heat conductivity of greater than 30 W/m/K. The perforations extend in-line through the stacked sheet metal plates and hold the catalyst particles. The stacked plates are surrounded around the edges by a sleeve separating the gas inlet zone (4) from the gas outlet zone (5). The gas inlet zone (4) from the gas outlet zone (5) are linked only via the perforations (1) in the panels. The panels are sheet metal (e.g. aluminum, copper, silver or their alloys), ceramic or graphite. The perforation diameter is less than 6 mm.

Abstract: A multitube fixed bed reactor and the use of such a reactor for carrying out catalytic gas-phase reactions, in particular for carrying out exothermic and endothermic catalytic gas-phase reactions such as the preparation of phthalic anhydride (PA), acrylic acid, methacrylic acid (MAA), acrolein, maleic anhydride (MA), glyoxal, phosgene, hydrocyanic acid or vinyl formamide (VFA). In a relatively large multitube reactor in which a large amount of heat of reaction is generated owing to the numerous catalyst tubes ( 17 ) and has to be removed, it is proposed that the ratio of tube spacing t to external tube diameter d a be made dependent on the reactor diameter or on the external tube bundle diameter d RBa . At an external diameter of the catalyst tube bundle ( 18 ) of more than 4 meters, a ratio of tube spacing d to external tube diameter d a of at least 1.3 is preferred.
