Abstract
A fluidized-bed reactor for carrying out a gas-phase reaction, in which a gaseous reaction mixture flows from the bottom upward through a heterogeneous particulate catalyst forming a fluidized bed and internals are arranged in the fluidized bed, wherein the internals divide the fluidized bed into a plurality of cells arranged horizontally in the fluidized-bed reactor and a plurality of cells arranged vertically in the fluidized-bed reactor, with the cells having cell walls which are permeable to gas and have openings which ensure an exchange number of the heterogeneous particulate catalyst in the vertical direction in the range from 1 to 100 liters/hour per liter of reactor volume, is proposed.
