Beschreibung
Zusammenfassung:	The present invention relates to a reaction device with air-lift type internal circulation which includes:-a vertical cylindrical volume;-a vertical element positioned within said volume in such a way as to form an interspace with the walls of said volume, having a cross-section which is circular and orthogonal to the vertical axis of the element and with a variable internal diameter along said axis, said element being denoted "draft tube";-at least one gas distributor positioned on the bottom of said device; said device being characterised in that:-the ratio between the diameter of the internal vertical element and the internal diameter of the cylindrical volume ranges from 0.05 to 0.5, and-the ratio between the height of the vertical element and the height of the cylindrical volume is less than 0.5.
