Abstract: A method for continuous feeding of dry coal particles from essentially atmospheric pressure to the superatmospheric pressure level of a coal gasifier or coal liquefaction reactor is achieved by a series of screw feeding devices each partially boosting the pressure level of the coal in stages to provide the dry coal at reactor pressure.

Abstract: IRON OXIDE CONTAINING ORES ARE CONTINUOUSLY REDUCED IN AN UPFLOW FLUIDIZED BED HYDROGENATION PROCESS. THE ORE IS CONTINUOUSLY FED BY HOT REDUCING GAS TO THE REACTION ZONE, THROUGH A HEATER HAVING A HELICAL TRANSFER LINE COIL SO THAT THE IRON ORE IS PREHEATED TO ABOUT 900*F. AND PARTIALLY REDUCED PRIOR TO ENTERING THE REACTION ZONE.
