Abstract: A process for preparing chlorine in a fluidized-bed reactor, in which a gaseous reaction mixture comprising hydrogen chloride and oxygen flows from the bottom upward through a heterogeneous particulate catalyst forming a fluidized bed, wherein the fluidized bed is provided with internals which 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.

Abstract: A process for preparing aromatic amines by catalytic hydrogenation of the corresponding nitro compound in a fluidized-bed reactor, in which a gaseous reaction mixture comprising the nitro compound and hydrogen flows from the bottom upward through a heterogeneous particulate catalyst forming a fluidized bed, wherein the fluidized bed is provided with internals which 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.
