REACTOR WITH ONE OR MORE FLUID SUPPLY LINES AND FLOW DISTRIBUTION DEVICE FOR SAID FLUID STREAMS

摘要

Reactor comprises at least one supply line (1) for at least one fluid stream exhibiting a temperature of >= 200[deg] C at one end of the reactor, at least one discharge line (2) for the reaction mixture at the other end of the reactor, baffles (5) for supplying or discharging the heat and/or increasing the surface area, and an uniform distribution means. A main flow direction (3) is defined through the reactor. The total cross-sectional area for the supply lines ( Ai) is less than the maximum cross-sectional area (AR) of the reactor. Reactor comprises at least one supply line (1) for at least one fluid stream exhibiting a temperature of >= 200[deg] C at one end of the reactor, at least one discharge line (2) for the reaction mixture at the other end of the reactor, baffles (5) for supplying or discharging the heat and/or increasing the surface area, on which the reaction is carried out, an uniform distribution means, which is arranged in the main flow direction in front of the baffles in the reactor, and an opening for the passage of at least one fluid stream. A main flow direction (3) is defined through the reactor. The total cross-sectional area for the supply lines ( Ai) is less than the maximum cross-sectional area (AR) of the reactor. The uniform distribution means has at least two flat elements (4). The uniform distribution means has an expansion in the main flow direction through the reactor. The expansion is less than the extension direction perpendicular to the main flow direction through the reactor by at least a factor 2, preferably at least a factor 10. The uniform distribution means extends through the entire cross section of the reactor and is arranged perpendicular to the main flow direction through the reactor. The hydraulic diameter (dh) of at least two flat elements is defined by an equation comprising (dh) is equal to 4 V1/ O1, where V1 is the fluid-flow volume of the flat element and O1 is surface of the flat element wetted by the fluid. The value of (dh) is 0.5 mm to 1/10 of the hydraulic diameter of the reactor. At least two successive flat elements are mutually spaced in the main flow direction through the reactor by less than half the hydraulic diameter of the reactor, greater than 10 times the hydraulic diameter of directly positioned upstream flat element, and 1/4 the hydraulic diameter of the supply line with the maximum cross-sectional area. An independent claim is also included for using the reactor for carrying out reactions at reaction temperatures of 200-1000[deg] C, preferably 500-1000[deg] C.
