摘要
A reactor for carrying out heterogeneous-phase reactions, in particular gas/liquid reactions with a continuous liquid phase and a dispersed (discontinuous) gas phase, is described, in which, in a horizontal plane, a substantially vertically upward-directed flow of the reaction medium takes place in a first region of the reactor cross-section and a substantially vertically downward-directed flow takes place in another region of the reactor having a device for dispersing the discontinuous phase such as a dispersing screen, substantially only in the regions with upward-directed flow. The reactor is here designed in such a way that free flow of the reaction medium from regions with downward-directed flow to regions with upward-directed flow is possible in the region of the dispersing device. The preferred use of the proposed reactor is the exothermic oxidation of p-xylene and monomethyl p-toluate with air in the so-called Witten DMT process.
