Patent number: 9174192Abstract: The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m.Type: GrantFiled: January 19, 2010Date of Patent: November 3, 2015Assignee: BASF SEInventors: Joaquim Henrique Teles, Peter Resch, Wilhelm Ruppel, Ulrike Wegerle, Wolfgang Gerlinger, Beatrice Röβler-Feigel, Anton Meier, Christian Müller
