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.
