Beschreibung
Zusammenfassung:	A reactor for gas-liquid mass transfer between a gas and a liquid or slurry includes a tank for receiving the liquid or slurry having a wall; a drive shaft; an upward pumping impeller; and an aerating apparatus disposed above the upward pumping impeller and extending between the drive shaft and the wall of the tank at a first distance (d1) from the drive shaft and at a second distance (d2) from the wall of the tank, the aerating apparatus encircling the drive shaft at least partially. The aerating apparatus has an outward inclined or curved inner surface for directing at least a part of the flow over the inner surface.
