Abstract: Reactor comprises square heat transfer sheet modules which form a slit which can be filled with a heterogeneous particulate catalyst and through which the reaction mixture flows, a sleeve which depressurizes the heat transfer sheet modules and fully surrounds the modules, and sealing elements. The fluid reaction mixture flows only through the slit, except through the reaction interior spaces. Reactor comprises square heat transfer sheet modules (1) comprising two or more right-angled heat transfer sheets (2) parallel to each other, to form a slit (3) which can be filled with a heterogeneous particulate catalyst and through which the reaction mixture flows, a sleeve which depressurizes the heat transfer sheet modules and fully surrounds the modules, and sealing elements (7) arranged so that the fluid reaction mixture flows only through the slit, except through the reaction interior spaces, defined by the caps. The sleeve comprises a cylinder casing (4) and caps (15, 16) to close the casing at both ends.

Abstract: Preparation of at least one partial oxidation and/or ammoxidation product of a hydrocarbon involves partially dehydrogenating at least one saturated hydrocarbon under heterogeneous catalysis and using the resulting product gas mixture for heterogeneously catalyzed partial oxidation and/or ammoxidation of the partially dehydrogenated hydrocarbon present in the product gas mixture. Preparation of at least one partial oxidation and/or ammoxidation product of a hydrocarbon involves: (a) dehydrogenating a saturated hydrocarbon (preferably propane or isobutene) using a heterogeneous catalyst in the gas phase to form a product gas mixture, comprising one or more partially dehydrogenated hydrocarbon, leaving constituents present in the product gas mixture, other than the saturated hydrocarbon and the partially dehydrogenated hydrocarbon; or partly or fully removing them to obtain a product gas mixture; and (b) partial oxidizing and/or ammoxidizing the product gas mixtures using one or more heterogeneous catalyst. The method includes at least one mechanical separation operation so that solid particles present in the gas mixtures can be removed.

Abstract: Acrolein and acrylic acid are produced from propane and propene by absorption/desorption of propane and propene from a gas mixture followed by oxidation, in which no heterogeneously catalyzed dehydrogenation of propane occurs between the desorption and oxidation stages without addition of oxygen. Acrolein and acrylic acid are produced from propane and propene by: (a) separation of propane and propene from a gas mixture (A) by absorption in an absorption medium; (b) separation of propane and propene from the absorbent to give a mixture (B) containing propane and propene; and (c) using mixture (B) for oxidation to the required product(s). In this process, no catalytic dehydrogenation of propane without the addition of oxygen is carried out between stages (b) and (c).

Abstract: The invention relates to a method for carrying out the two-stage catalytic gas phase oxidation of propene to form acrylic acid. The inventive method provides that, in a multitube fixed-bed reactor, the reaction gas starting mixture having a propene load >/= 160 Nl propene / l.h is firstly conducted over a fixed-bed catalyst feed material (1), which is located in two successive temperature zones A, B, and afterwards, is conducted over a fixed-bed catalyst feed material (2), which is accommodated either in another temperature zone C or in two additional temperature zones D, E. The temperature of zone A is maintained at a lower temperature than that of zone B, and the temperature of zone D is maintained at a lower temperature than that of zone E.

Abstract: The invention relates to a reactor for partial oxidation of a fluid reaction mixture in the presence of a heterogeneous particulate catalyst. Said reactor comprises one or several cuboid heat-transfer sheet modules (1) which are each composed of two or several right-angled heat-transfer sheets (2), arranged parallel to each other such as to form a slit (3) which can be filled with the heterogeneous particulate catalyst and through which the fluid reaction mixture flows, the heat of reaction being absorbed by a heat carrier which flows through the heat-transfer sheets (2) and at least partially evaporates. Said reactor also comprises a mainly cylindrical envelope (4, 15, 16) which depressurizes the heat-transfer sheet modules and fully surrounds said modules, said envelope being composed of a cylinder casing (4) and of caps (15, 16), closing said casing at both ends, the longitudinal axis of which extends parallel to the plane of said heat-transfer sheets (2). Said reactor finally comprises one or several sealing elements (7, 23), arranged so that the fluid reaction mixture flows only through the slit (3), except through the reactor interior spaces, defined by the caps (15, 16).
