A reactor having a vertically extending vessel wall (2) is provided with a plurality of staggered elongated parallel tubes (8) adapted for being filled with catalyst material and substantially vertically extending between an upper tube plate (10) and a lower tube plate (9), means (12, 13) for circulating a heat transfer medium between the tube plates (9, 10) alongside the tube walls (8), inlet means (3, 17, 18) above the parallel tubes (8) for distributing fluid in the form of one or more sprays and gas over the plurality of tubes (8) and outlet means (4, 20) situated below the plurality of tubes (8) for removal of fluids from the reactor, wherein the plurality of staggered tubes (8) are arranged in rows such that the tubes of adjacent rows are staggered, and wherein upper tube plate (10) is provided with openings (15), having a lower part in which the tubes (8) are closely fitted and having a substantially concentric upper part diverging in upward direction, the upper ends of the adjacent openings having edges in common in such a manner that the upper end of the upper tube plate (10) is formed by edges (16) arranged in a hexagonal honeycomb ribbed configuration.

An apparatus for performing a chemical reaction in a reaction vessel, which reaction vessel comprises a normally vertically extending outer vessel wall, means defining a fluid collection zone situated in the bottom of said vessel, an upper tube plate situated in the upper portion of said vessel with means defining a plurality of hexagonal openings having a honeycomb configuration within said upper tube plate, a lower tube plate permeable by fluids but impermeable to solid material situated in the lower portion of said vessel, means for circulating a heat transfer medium situated intermediate said upper and lower tube plates, a fluid introduction zone having fluid inlet means comprising a plurality of inlet fluid spray nozzles situated in axial alignment with said plurality of openings in said upper plate and designed to emit a spray pattern for spray of said inlet fluid in a hexagonal honeycomb configuration substantially congruent to the honeycomb configuration of hexagonal openings to provide for passage directly downward in said hexagonal openings in said upper tube plate and thereby uniform distribution of said inlet fluid over said upper tube plate and to thereby inhibit sideward flow of said inlet fluid over said tube plate and a fluid inlet means situated in said vessel at a point elevated with respect to said upper tube plate, a fluid outlet means situated in the bottom of said vessel, and a plurality each having a top portion of staggered parallel tubes and extending from and in intercommunication with a respective one of said hexagonal openings in said upper tube plate and extending to a point in contact with said lower tube plate, wherein said staggered tubes are in intercommunication with said upper plate through said plurality of hexagonal openings in said upper plate, each of said hexagonal openings having an upper part and a lower part, wherein said lower part is closely fitted to the top portion of a respective parallel tube and wherein said upper part is substantially concentric with said lower part and diverging in an upward direction to an upper end, said upper end being situated contiguous to and adjacent with respect to the edges of other upper ends of said openings to define said honeycomb configuration in said upper tube plate.
