    Abstract: A combined gasification/devolatilization process for coal in coal residues is disclosed wherein hydrogen rich volatiles are recovered prior to gasification of the coal. The recovery of hydrogen volatiles is dependent upon the rapid heating of coal obtained by admixture with hot char previously gasified in a riser with steam and a catalyst if necessary. The hot char is provided by combustion of devolatilized coal in a fluid bed regenerator. Alternative systems are provided for purifying the devolatilized coal prior to its charring.

    Abstract: Coal is transported through a hot carbonizing furnace chamber successfully on two endless traveling chain grates, the first of which is higher than the second and the second being run at a slower speed than the first so as to form a thicker bed than the coal on the first grate. Air is fed through the coal on the first grate in sub-stoichiometric amounts at low velocity so as to drive off the volatiles while air and steam are fed to the coal in the second grate in amounts sufficient to burn the coal. Gaseous by-products are exhausted from the furnace chamber and ashes are discharged through a conventional take-off.

    Abstract: A kiln having pyrolysis, gasification and cooling horizontal zones, divided over its height into vertical chambers by vertical dividing walls, and having flues with vents housed in the dividing walls and the walls of the outer enclosure for injecting reaction fluids and fumes and for drawing off gases and vapors.In the gasification zone, the dividing walls have diffusion panels adjacent diffusion chambers. The panels are connected to the reaction fluid supply and are of a height which corresponds substantially to the height of the panel.The vertical chambers form modular cells through which the granulated mineral flows continuously without encountering obstructions in the form of irregularities.
