Abstract

The present invention relates to a process and an apparatus for dispersing a gas in a liquid flowing within a vertical cycle through two reaction zones arranged in parallel within a reactor, the liquid/gas mixture flowing upwards in the first reaction zone due to the air-lift pump effect and being degassified at the transition from the first reaction zone to the second reaction zone and the completely or partly degassified liquid flowing down and the liquid being remixed with gas (preferably air) at the transition from the second to the first reaction zone below the two reaction zones.
