An apparatus and method for mixing and distributing solid material in which the material is continuously introduced into a vessel and a pressurized gas is introduced into the lower portion of the vessel at a velocity sufficient to pass upwardly through the material in the vessel to promote mixing of the material. A plurality of outlets are disposed in an angularly spaced relation along the vessel for permitting the material to continuously discharge to a plurality of selected locations. The excess gas in the vessel is removed, cleaned and introduced back into the vessel.

A process for the desulfurization of coal and apparatus for carrying out the process. The process includes the steps of: first, treating dry coal particles with dry chlorine gas; and, second, treating the coal particles with a purging gas. The purging gas may be, for example, dry steam or an inert gas, such as nitrogen or carbon dioxide. The apparatus includes a chlorinator means for treating the dry coal particles with dry chlorine gas and a stripper means for treating the coal particles with a purging gas.
