Abstract

The invention relates to a device and a method for introducing gas into a fluidized bed reactor, the device having at least one gas inlet pipe (2, 3) above and/or below the fluidized bed, characterized in that the gas inlet The tubes (2, 3) have gas flow swirl means at and/or upstream of their openings.

Description

technical field [0001] The invention relates to a device for introducing gas into a fluidized bed, and to a fluidized bed reactor comprising the gas introducing device. The invention also relates to a process for the oxychlorination of ethylene to form 1,2-dichloroethane using a fluidized bed reactor according to the invention. Background technique [0002] Fluidized bed reactors generally include a catalytic bed of solid fine-grained particles, where the catalytic bed usually acts as a catalyst for the reaction to take place. The substances reacting in the reactor are generally gases, and the reaction products leaving the reactor at the top of the reactor are likewise gases. Both introduction and mixing of the reactants take place in the lower part of the reactor, in particular above and / or below the fluidized bed. The gas inlet and distribution system in which the reactants mix and come into contact with the catalyst plays an important role in the optimization of the rea...
