ABSTRACT:
Coking of residual oil and devolatization/partial gasification and desulfurization of solid particulate fuel are carried out in a single reactor. The particulate fuel is burned in a combustion zone in the bottom of the reactor. A bed of particulate fuel is fluidized above the combustion zone with gases rising from the combustion zone. The fluidized bed is maintained at a temperature which cokes the residual oil and volatizes the particulate fuel. A high temperature, low velocity zone is maintained between the combustion zone and the fluidized bed for calcination and desulfurization of the solid fuel.
