Publication number: 20120157719Abstract: 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: ApplicationFiled: January 19, 2010Publication date: June 21, 2012Applicant: BASF SEInventors: Joaquim Henrique Teles, Peter Resch, Wilhelm Ruppel, Ulrike Wegerle, Wolfgang Gerliing, Beatrice Rössler-Feigel, Anton Meier, Christian Müller

Publication number: 20110306812Abstract: In a process for the cooligomerization of olefins, an olefin starting material comprising olefins having n carbon atoms and olefins having 2n carbon atoms is reacted over an olefin oligomerization catalyst to give a reaction product. The process is carried out under such conditions that the conversion of olefins having 2n carbon atoms is less than 10%. Both the cooligomer having 3n carbon atoms and the olefin having 2n carbon atoms which has been separated off from the reaction product have a high hydroformylatability.Type: ApplicationFiled: June 14, 2011Publication date: December 15, 2011Applicant: BASF SEInventors: Wolfgang Rohde, Qiang Miao, Stefan Bitterlich, Gauthier Luc Maurice Averlant, Hans-Guenter Wagner, Beatrice Rößler-Feigel
