Nielsen, R H

This patent describes an apparatus for feeding a mixture of fluidized solids and a fluid feed material to be contacted therewith, comprising: a lift pot having a longitudinal axis, an upper end portion, a lower end portion, and an interior surface, the upper end portion having an outlet therein, and the interior surface defining a contacting zone adjacent the upper end portion and a feeding zone located below and in contact with the contacting zone; solids inlet means in communication with the feeding zone for introducing solids into the feeding zone; first fluidizing means located in the lower portion of the feeding zone for fluidizing solids in the feeding zone, increasing the velocity level of fluidized solids in the feeding zone and moving such fluidized solids to an upper portion of the feeding zone; second fluidizing means located in an upper portion of the feeding zone above the solids inlet means for further increasing the velocity level of fluidized solids in the feeding zone and moving such fluidized solids from the feeding zone into the contacting zone; atomization nozzle means in fluid flow communication with the interior of the lift pot for atomizing fluid and for injecting thus atomized fluid upwardly into the contacting zone, the atomization nozzle means being positioned separately from the first and second fluidizing means.
