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 gas distributor (1) has a perforated curved surface with concave and convex sides (4, 5). Its edge conforms with the inner wall of the equipment (2) near the supply opening (3). The concave side faces and surrounds the supply opening (3) at the inner wall. The equipment is a cylindrical vessel with dished- or hemispherical ends (6), the opening (3) being in one of them. The distributor has a central flat end (7) and a peripheral region (8), in an overall blunt conical form. The perforations are holes or slots. Their open area ratio is greater in the central region (7) than in the peripheral region (8), being 2-20% and 4-40% respectively. An Independent claim is included for the method of mounting a gas distributor.

Abstract: A reactor for endothermic reactions of gaseous or gas-solid mixtures has heating block(s) filling the reactor cross-section which are electrically insulated from the reactor wall and optionally from one another, each block being provided with power connections and consisting of open-cell foam which heats up when a voltage is applied and transfers heat to the mixture.

Abstract: A process for the preparation of maleic anhydride by heterogeneously catalyzed gas-phase oxidation in a reactor with feed for the reaction mixture at one end of the reactor and discharge of the product mixture at the opposite end of the reactor, and with devices for dissipating the heat of reaction which are arranged in the reactor interior and through which a heat-exchange medium flows and which are designed as heat-exchanger plates.

Abstract: Ordered packing (1) for a reactor has flow deviating sheets (A, B) arranged in the longitudinal direction of the reactor and parallel with a heating/cooling casing. Corrugated flow deviating sheets (A) are alternately arranged with planar flow deviating sheets (B) forming flow deviating channels (2). The flow deviating sheets (A) completely fill the cross-section of the reactor and the flow deviating sheets (B) expose an edge gap (3) on the inner wall of the reactor. Preferred Features: The edge gap is formed in a non uniform manner over the cross-section of the reactor having the largest possible radial extension in regions of the inner wall of the reactor into which flow deviating channels protrude and having the smallest possible radial extension in which flow deviating channels do not protrude. The flow deviating channels contain inert material and/or catalyst material.

Abstract: Pump comprises a housing containing a guide pipe and having an opening in its lower part, via which heat transfer medium removed from the lower region of a reactor flows into the housing. Pump comprises a housing (14) containing a guide pipe (13) and having an opening (15) in its lower part, via which heat transfer medium (6) removed from the lower region of a reactor flows into the housing. The medium further flows up between the inner wall of the housing and the outer wall of the guide pipe via a heat exchanger (18), via an opening in the upper region of the pipe into the inner chamber of the pipe, then via an opening in the lower region of the pipe into a further intermediate chamber between the inner wall of the housing and the outer wall of the guide pipe, and finally into the upper region of the intermediate chamber between contact tubes. Preferred Features: The pump is a propeller pump having three or more blades. The housing is rectangular or circular. Baffle plates (19) are arranged in one or more deviating regions of the housing for the heat transfer medium.

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.
