Abstract

A reactor for carrying out a three-phase reaction of a liquid phase, a gaseous phase, and a catalyst over a fixed catalyst bed is disclosed. The liquid and gaseous phases are passed through the reactor via a mixing and distribution device positioned over the fixed catalyst bed. The mixing and distribution device includes a trough distributor for the liquid phase, having trough-shaped channels, outlet tubes in the trough-shaped channels for the liquid phase, a distributor plate below the trough distributor, and vertical nozzles, having one or more openings for the gaseous phase and one or more openings, arranged below the openings for the gaseous phase. For entry of the liquid phase, the nozzles are installed so that, at a predetermined liquid feed rate, the surface of the liquid on the distributor plate is below the openings for the gaseous phase and above the openings for the liquid phase.
