ABSTRACT:
Disclosed is a method for fluidizing a dense phase bed of solid particles, preferably a method for fluidizing a dense phase bed of solid catalyst particles. The method includes the steps of continuously supplying a flowing fluid stream in a downward direction within an enclosed volume; contacting an upper surface of a dense phase bed of solid particles resting within the enclosed volume with the downward flowing fluid stream; continuously directing the flowing fluid stream into the dense phase bed of particles to form a continuous fluidized bed of solid particles within the enclosed volume; directing the flowing fluid stream in an upward direction after contacting the upper surface of the dense phase bed; and collecting the flowing fluid stream.
