Figure 13.2 Schematic diagram of the
60 L concentric tube airlift reactor. The
reactor is divided in eight sections for
sampling purposes (sections 1 to 5
correspond to the gas-liquid separator
and section 6 is a transition section
between the downcomer (7) and the
riser (8) (Freitas and Teixeira, 1998a).
