Abstract: A process for heterogeneously catalyzed partial dehydrogenation of a hydrocarbon, in which a reaction gas mixture input stream comprising the hydrocarbon to be dehydrogenated is conducted through a fixed catalyst bed disposed in a shaft and the reaction gas mixture input stream is obtained in the shaft by metering an input gas II comprising molecular oxygen upstream of the fixed catalyst bed into an input gas stream I which comprises molecular hydrogen and the hydrocarbon to be dehydrogenated and is flowing within the shaft toward the fixed catalyst bed.

Abstract: The present invention relates to an apparatus (1) for separation of a target product from a liquid phase P comprising the target product, comprising at least one primary space (3) for a heat transfer medium W, at least one first feed unit (5a) and one first removal unit (5b) for the heat transfer medium W, at least one secondary space (7) for the liquid phase P, at least one second feed unit (9) for the liquid phase P, at least one crystallization surface (13) which divides the primary space (3) and the secondary space (7), at least one second removal unit (15) for the target product and at least one application unit (11) for a liquid phase P0 essentially directly to the crystallization surface (13) or the surfaces of lines that conduct the heat transfer medium W. The present invention further relates to a process for removing a target product from a liquid phase P comprising the target product.
