<p>REACTOR FOR NON-ISOTHERMIC REACTIONS AND PROCESS FOR THE PREPARATION OF HYDROCARBONS USING SUCH A REACTOR Reactor comprising a vertically extending vessel (2) provided with a plurality of 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) along the tubes (8), inlet means (3, 17, 18) above the tubes (8) for distributing liquid in the form of one or more sprays and gas over the plurality of tubes (8) and outlet means (4, 20) below the plurality of tubes (8) for removal of liquid and gas from the vessel (2), wherein the plurality of tubes (8) are arranged in rows such that the tubes of adjacent rows are staggered, and wherein the upper tube plate (10) is provided with holes (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 adjacent holes 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 configuration. The invention further relates to a process for the preparation of hydrocarbons using such reactor.</p> |
