ABSTRACT:
A fluidized stream of coal particles is introduced into the bottom of a vertical reaction zone in a fluidized bed process at a velocity of greater than about 200 ft/sec in a vertically upwards direction, wherein agglomeration of the fluidized bed is prevented. A separate liquid hydrocarbon stream is simultaneously introduced as a separate injection stream in a vertically upwards direction, said coal particles and said liquid hydrocarbons being rapidly and uniformly dispersed within the fluidized bed and reacted therein with a suitable reagent.
