    • PROBLEM TO BE SOLVED: To provide a continuous heterogeneously catalyzed partial dehydrogenation of a hydrocarbon in the gas phase and in the presence of molecular oxygen, in which a part of a product gas is recirculated to a reaction zone, and a reactor for carrying out such a process. SOLUTION: In the process, a reaction gas containing at least one hydrocarbon to be dehydrogenated is supplied to the reaction zone; the reaction gas is passed in the reaction zone through at least one fixed catalyst bed, wherein the reaction gas is subjected to catalytic dehydrogenation to produce molecular hydrogen and at least one partial dehydrogenated hydrocarbon; the reaction gas, before and/or after entering the reaction zone, is added with a gas containing at least one molecular oxygen-containing gas; the molecular oxygen partially oxidizes the molecular hydrogen contained in the reaction gas in the reaction zone to form water steam; a gas product containing the molecular hydrogen, water steam, at least one dehydrogenated hydrocarbon, and at least one hydrocarbon to be dehydrogenated is withdrawn from the reaction zone; at least one hydrocarbon to be dehydrogenated in the gas phase is partially dehydrogenated by a continuous heterogeneous catalyst. In the partial dehydrogenation method using the continuous heterogeneous catalyst, the reaction gas withdrawn from the reaction zone is divided into two parts being the same in composition, one of which is recycled into reaction zone as a circulating gas.
