摘要： 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).

摘要： 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).

摘要： Acrolein and/or acrylic acid is prepared by feeding to a first reaction zone A at least two gaseous, propane-containing feed streams comprising fresh propane, and in reaction zone A, subjecting their propane fed to a heterogeneously catalyzed dehydrogenation to obtain a product gas mixture A comprising propane and propylene. Preparation of acrolein and/or acrylic acid involves feeding to a first reaction zone A at least two gaseous, propane-containing feed streams having fresh propane and in reaction zone A, subjecting their propane fed in this way to a heterogeneously catalyzed dehydrogenation to obtains a product gas mixture A comprising propane and propylene; conducting product gas mixture A out of reaction zone A and in a first separation zone A, removing a portion of the constituents other than propane and propylene in product gas mixture A and using remaining product gas mixture A' comprising propane and propylene; in a second reaction zone B to charge an oxidation reactor and, in the oxidation reaction, subjecting the propylene present in product gas mixture A' to a catalyst gas phase partial oxidation with molecular oxygen to give a product gas mixture B having acrolein or acrylic acid as the target product and also excess molecular oxygen; and conducting product gas mixture b out of reaction zone B and in a second separation zone, removing target product present in product gas mixture B, and of the remaining residual gas having unconverted propane, molecular oxygen and any unconverted propylene as one of the two-propane-containing feed streams into reaction zone A, where this recycling into he reaction zone A along the reaction path of the catalyzed dehydrogenation of propane in reaction zone A is effected such that at the feed point, >=5 mol.% of the propane fed to reaction zone A via the other feed streams has already been converted under dehydrogenating conditions in reaction zone A.

Partial oxidation in the gas phase of 3C and/or 4C precursor compounds to (meth)acrolein and/or (meth)acrylic acid in the presence of a heterogeneous particulate catalyst in a reactor having cuboidal thermoplate modules which are each formed from two or more rectangular thermoplates arranged parallel to each other while in each case leaving a gap which can be filled with the heterogeneous particulate catalyst and is flowed through by the fluid reaction mixture, the heat of reaction being absorbed by a heat carrier which flows through the thermoplates and thus at least partly evaporating; having a predominately cylindrical shell which releases the pressure at the thermoplate modules, completely surrounds them and comprises a cylinder jacket and hoods (15, 16) which seal it at both ends and whose longitudinal axis is aligned parallel to the plane of the thermoplates; and having sealing element(s) which are arranged in such a way that the fluid reaction mixture, apart from flowing through the reactor interior spaces bounded by the hoods, only flows through the gap.
