    Abstract: PROBLEM TO BE SOLVED: To provide a reactor in which a hot spot is difficult to occur in a catalyst packed inside the reactor, having little pressure drop when fluid reaction mixtures pass through the catalyst, and in which the heterogeneous catalyst is packed. SOLUTION: A fixed-bed reactor is described for carrying out reactions of fluid reaction mixtures in the presence of a particulate heterogeneous catalyst having a structured packing which forms interstices in the reactor interior, in which the quotient of the hydraulic diameter for the fluid flow through the structured packing and the equivalent diameter of the catalyst particles is in the range from 2 to 20, preferably in the range from 5 to 10, to such an extent that the catalyst particles are introduced into the interstices, loosely distributed and discharged under the action of gravity.

    Abstract: The invention relates to a liquid distributor for vacuum distillation, comprising an admission (1) and means for supplying the liquid to distributor channels (5) which comprise openings for feeding the liquid to be distributed to a column packing (7). The inventive liquid distributor is characterised in that the supply means comprise a pipe manifold (4) which is provided with pipes and horizontally arranged in a plane, said pipe manifold comprising openings (3) for supplying liquid to the distributor channels (5).

    Abstract: Fixed bed reactor comprises a structured packing (1) forming intermediate chambers (3) inside the reactor. The quotient of the hydraulic diameter for the fluid stream through the packing and the equivalent diameter of catalyst particles (4) is in the region of 2-20, preferably 5-10. The catalyst particles are introduced into the intermediate chambers under the action of gravity, loosely distributed and removed. Preferred Features: The structured packing has a cross-channel structure, and comprises packing sheets for insertion along the longitudinal axis of the reactor. The packing has a reduced flow resistance on its surface.
