Device for reaction with internal circulation of air lift type and fermentation process using said device.

摘要

The present invention relates to a device for reaction with internal circulation of air lift type which include: - a vertical cylindrical volume; a vertical element positioned inside said VOlume thus forming 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 an internal diameter variable along the said axis, said element being indicated. A suction tube? ,At least one gas distributor positioned at the bottom of said device, said device being characterized by the fact that: - the relationship between the diameter of the vertical element and inner diu00e2metro internal cylindrical volume varies from 0.05 to 0.5, and the relationship between the height of the vertical element and the height of the cylindrical volume is less than 0.5.
