Abstract
A process for treating a liquid with a gas in a circulatory reactor, in which the gas is introduced by a jet of liquid into a circulating liquid, is entrained downwards in a tube, rises in an annular space surrounding the tube and--if it has not reacted completely--is again entrained downward over the upper edge of the tube. Using the process according to the invention, a very uniform gas distribution and, in the case of heterogeneous reactions, also a very uniform distribution of the suspended catalyst, is achieved over the entire reaction space.
