Agitation effects on hydrogen gas production byCitrobacter intermedius

Transport phenomena, reactor design and scale-up

This review will cover the area of impeller-mixed stirred-tank reactors. In addition, it will consider bubble columns, in which air or gas is passed up a liquid filled column through distribution plates covering the full area of the column, and also airlift reactors, in which the air is confined in a channel by means of a loop or draft tube designed to impart a certain type of overall circulatory pattern to the entire tank. There is considerable interest in the kinetics inside the solid part of various kinds of immobilized solid pellet type of enzymes and catalysts. The use of these particles in fixed bed reactors is also covered.
