Abstract

An oxidizing gas is injected through a nozzle into a bed of carbonaceous particles in a downward direction at an angle of declination at least as great as the angle of repose of the bed particles and at a gas inlet velocity of about 50 to 500 feet per second to supply the gas needed to fluidize the bed of carbonaceous particles.
