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 method for the heterogeneously catalysed partial gas phase oxidation of acrolein to form acrylic acid, whereby the initial mixture of reaction gas is oxidised on a fixed-bed catalyst bed which consists of at least two fixed-bed catalyst bed zones and is arranged in two successive temperature zones A and B. The transition from temperature zone A to temperature zone B does not coincide with a transition from a fixed-bed catalyst bed zone to another fixed-bed catalyst bed zone.

摘要： Preparing at least one organic target compound (I) by heterogeneously catalyzed gas phase partial oxidation of at least one organic precursor compound with molecular oxygen in at least two oxidation reactor systems comprising catalyst charges and are operated in parallel to obtain at least two product gas streams (II) each comprising (I) and each stemming from one of the at least two oxidation reactor systems and subsequent removal of (I) from (II) to obtain at least one crude target product stream, where the process comprises before, during and/or after the removal, mixing together (II). Preparing at least one organic target compound (I) by heterogeneously catalyzed gas phase partial oxidation of at least one organic precursor compound with molecular oxygen in at least two oxidation reactor systems comprising catalyst charges and are operated in parallel to obtain at least two product gas streams (II) each comprising (I) and each stemming from one of the at least two oxidation reactor systems and subsequent removal of (I) from (II) to obtain at least one crude target product stream, where the process comprises before the removal, mixing together (II); or in the course of the removal, mixing together at least two of any target product-comprising subsequent streams obtained on the route from (II) to the at least one crude target product stream; and/or after the removal from (II), mixing together any crude target product streams obtained in the course of the removal, to form a mixture stream, where at least one of the catalyst charges of the at least two oxidation reactor systems operated in parallel, over which the target compounds comprised in the mixture stream were formed, comprises at least one portion of catalyst over which the heterogeneously catalyzed gas phase partial oxidation has already been carried out longer than over all portions of catalyst of the at least one other catalyst charge. An independent claim is included for an apparatus comprising two oxidation reactor systems which are charged with catalysts that are suitable for the preparation of (I) by heterogeneously catalyzed partial oxidation of an organic precursor compound and at whose outlet is disposed in each case a line for the removal of the product gas stream comprising (I) from the particular oxidation reactor system, which lines are combined with increasing distance from the two oxidation reactor systems to give a product gas line which leads to an apparatus in which the product gas stream can be condensed partly or fully, where the catalyst charge of one of the two oxidation reactor systems comprises at least one portion of catalyst over which more target product has already been generated than over the portions of catalyst of the catalyst charge of the other oxidation reactor system.
