    Abstract: The invention relates to a tube bundle reactor having a flat feed dome. Alternatively, the discharge dome can also be designed flat. The flat design reduces the reaction heat developing in the hood in reaction types that take place not only in the tube bundle (non-catalyzed reactions and reactions with homogenously distributed catalyst). Undesired reactions that already take place in the dome due to accumulated heat are thus heavily suppressed, whereby greater selectivity in temperature-sensitive reactions is achieved. Additionally, the temperature distribution within the domes can be precisely controlled. The tube bundle reactor comprises a tube bundle that has a feed end connected to a feed dome of the tube bundle reactor, wherein the feed dome is designed in a flat shape having a cross-sectional surface at the feed end and an inner volume, and the ratio of the inner volume to the cross-sectional surface is less than 0.35 m. The invention is furthermore implemented by a method for operating a tube bundle reactor, comprising: introducing a reactant mixture into a tube bundle and converting at least a portion of the reactant mixture into a product inside the tube bundle. The introduction step comprises: feeding the reactant mixture into an inner space of a feed dome of the tube bundle reactor and forwarding the reactant mixture into a feed end of the tube bundle in the form of a fluid flow. The fluid flow has a cross-sectional surface upon entering the feed end and the inner space of the feed dome through which the fluid flows has an inner volume; wherein the ratio of the inner volume to the cross-sectional surface is less than 0.35 m.

    Abstract: A process for producing propylene oxide comprising reacting propene with hydrogen peroxide in the presence of a catalyst to give a mixture (Gl) comprising propylene oxide, unreacted propene, and oxygen; separating propylene oxide from mixture (Gl) to give a mixture (GII) comprising propene and oxygen; and adding hydrogen to mixture (GII) and reducing the oxygen comprised in mixture (GII) at least partially by reaction with hydrogen in the presence of a catalyst comprising copper in elemental and/or oxidic form on a support, wherein copper is present on the support in an amount of 30 to 80 wt.-% based on the whole catalyst and calculated as CuO.
