Abstract 1. A PROCESS FOR TREATING HIGH RANK, MEDIUM VOLATILE BITUMINOUS COAL CONSISTING ESSENTIALLY OF: (A) PREPARING SAID COAL FOR OXIDATION IN A FLUIDIZED STATE, SAID PREPARATION CONSISTING ESSENTIALLY OF; (1) GRINDING SAID COAL TO A PARTICLE SIZE BETWEEN 100 MESH TO 325 MESH, (2) BRIQUETTING SAID GROUND COAL, (3) CRUSHING SAID BRIQUETTES TO A PARTICLE SIZE FROM ABOUT / INCH TO 100 MESH AND A POROSITY OF 0.05 CC./GM. TO 0.20 CC./GM., (B) FLUIDIZING SAID PREPARED COAL PARTICLES WITH A GAS CONTAINING FROM ABOUT 1% TO ABOUT 50% OXYGEN AT A TEMPERATURE FROM ABOUT 400* F. TO ABOUT 700* F. UNTIL THE OXIDATION NUMBER IS AT LEAST 85, (C) INJECTING WATER INTO THE FLUIDIZED SOLID/GAS MIXTURE OF SAID FLUIDIZED COAL PARTICLES TO CONTROL THE TEMPERATURE, (D) CARBONIZING SAID OXIDIZED COAL AT A TEMPERATURE IN THE RANGE OF ABOUT 1000* F. TO ABOUT 1200* F.; (E) ACTIVATING SAID OXIDIZED-CARBONIZED COAL WITH AN ACTIVATING GAS FROM THE GROUP CONSISTING OF STEAM AND AND OXYGEN CONTAINING GAS AT A TEMPERATURE IN THE RANGE OF ABOUT 1650* F. TO ABOUT 1950* F.; AND (F) RECOVERING AN ACTIVATED CARBON PRODUCT.
