Abstract
In a process for improving the gas distribution in air-lift loop reactors, the back-flowing, partially degassed liquid is divided into part streams prior to, during or after entry into the rising part of the loop. In this process, the cross-section of the sum of the part streams is intended to be smaller than the free cross-section of the rising part. The gas is passed into the part streams.
