Abstract: A mixer comprising sets of multi-bladed 45* axial impellers for providing substantially perfect mixing in a cylindrical reactor vessel having an L/D ratio greater than one. A first set of impellers located closest the impeller shaft pump downward while a second set of impellers located outwardly from the first set of impellers pump upward enhancing the flow along the vessel walls.
