Abstract: CASRBONIZATION OF BITUMINOUS COAL WHEREIN THE COAL IS ACIDIFIED WITH A LIQUID SULFONATING AGENT SUCH AS SULFURIC ACID OR OLEUM AND THEREAFTER CARBONIZED BY HEATING TO A TEMPERATURE IN THE RANGE OF 600*C. TO 900*C., THE HEATING RATE IN THE TEMPERATURE RANGE OF 400*C. TO 600*C. BEING IN EXCESS OF 10*C. PER MINUTE. THE ACIDIFIED COAL IS PREFERABLY DEACIDIFIED PRIOR TO CARBONIZATION BY HEATING AT A TEMPERATURE IN THE RANGE OF 400*F. TO 700*F. WITH OR WITHOUT A SWEEPING AIRSTREAM. ACID TREATMENT OF THE BITUMINOUS COALS PERMITS CARBONIZATION THEREOF AT AN ACCELERATED RATE WITHOUT CAKING DURING HEATING THROUGH THE TEMPERATURE RANGE OF 400*C. TO 600*C.

Abstract: ACID SLUDGE FORMED BY THE REACTION OF A MINERAL ACID WITH A RELATIVELY HIGH MOLECULAR WEIGHT HYDROCARBON IS USED TO BIND VARIOUS PARTICULATE CARBON MATERIALS INTO SHAPED ARTICLES WHICH MAY BE ACTIVATED. THE CARBON MATERIALS USEFUL IN THIS INVENTION ARE MATERIALS SUCH AS COKE, COAL, WOOD CHARCOAL OR ANY FORM OF CARBON PRODUCED BY CHARRING OR DESTRUCTIVE DISTILLATION OF WOOD, PEAT, LIGNITE, NUT SHELLS, CORN COBS, BONES, VEGETABLE MATTER GENERALLY, NATURAL AND SYNTHETIC ORGANIC POLYMERS, OR OTHER CARBONACEOUS MATTER, INCLUDING LIQUID AND LIQUEFIABLE PETROLEUM FRACTIONS. THE CARBON CONTENT OF MATERIALS USED FOR ADMIXING WITH THE ACID SLUDGE RANGES FROM ABOUT 10 PERCENT FOR BONE CHARCOAL TO 98 PERCENT OR HIGHER FOR SOME WOOD CHARS. THE APPROXIMATE BULK DENSITY OF USEFUL CARBON MATERIALS RANGES FROM 0.08 TO 2.50.
