    • 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. The invention is further implemented by means of a process for operating a tube bundle reactor, comprising: introducing a reactant mixture into a tube bundle and converting at least a proportion of the reactant mixture within the tube bundle to a product. The introducing comprises: feeding the reactant mixture into an interior of a feed hood of the tube bundle reactor and passing the reactant mixture on into a feed end of the tube bundle in the form of a fluid stream. The fluid stream has a cross-sectional area on entry into the feed end, and the interior of the feed hood through which the fluid stream flows has an internal volume; where the ratio of internal volume to cross-sectional area is less than 0.35 m.
    • 本发明涉及具有扁平进料罩的管束反应器。 或者,释放罩也可以具有平坦的设计。 在反应类型不仅在管束(未催化的反应和具有均匀分布的催化剂的反应)的情况下,扁平设计减少了发动机罩中产生的反应热。 这大大地抑制了由于积热而在罩中发生的不期望的反应,这在热敏反应的情况下实现了更高的选择性。 此外,可以精确地控制罩内的热分布。 管束反应器包括管束,其具有连接到管束反应器的进料罩的进料端,其中进料罩构造成平坦设计,在进料端具有横截面积,内部体积 ,内部体积与横截面积的比值小于0.35μm。 通过用于操作管束反应器的方法进一步实现本发明,其包括:将反应物混合物引入管束并将至少一部分管束内的反应物混合物转化成产物。 引入包括:将反应物混合物进料到管束反应器的进料罩的内部,并将反应物混合物以流体流的形式送入管束的进料端。 流体流在进入进料端时具有横截面面积,流体流流过的进料罩的内部具有内部容积; 其中内部体积与横截面积的比值小于0.35μm。
