ABSTRACT:
Apparatus for converting coal into a gas substitute in which a slurry mix of pulverized coal and water is heated to form an emulsion which is then successively passed through a catalytic chamber and a convertor chamber.
The catalyzed emulsion mix is heated to destructive distillation temperatures in the convertor chamber as superheated steam is introduced into the convertor chamber to effect a continuous destructive distillation process. The products of destructive distillation are then successively scrubbed, condensed and passed through separators to separate the solids and free hydrogen from the gaseous constituents with a portion of the distillation products not comprising the final natural gas substitutes being recycled to the burner as fuel to generate the heating temperatures necessary to perform the method. The condensed water is also recycled to form the slurry or the steam introduced into the convertor.
