Fuel briquets and their method of manufacture

Abstract

Abstract FUEL BRIQUETS WITH GOOD BURNING PROPERTIES, COMPLETE WATER RESISTANCE AND EXCELLENT STRENGTH ARE PRODUCED. THE METHOD OF PRODUCING THEM CONSISTS IN MIXING CARBON AGGREGATE COMPOSED OF PARTICULATE RAW COKE (SUCH AS DELAYED COKER, RAW PETROLEUM COKE) AND SUPPLEMENTAL PARTICULATE CARBON MATERIAL (WHICH PREFERABLY IS OR INCLUDES AN ANTHRACITIC MATERIAL), WITH 3-10% AMMONIUM LIGNIN SULFONATE AND WATER FOLLOWED BY BRIQUETTING AND HEAT TREATMENT AS A TEMPERATURE BETWEEN 200*C. AND 600*C. TYPICALLY FOR A PERIOD OF TIME BETWEEN 10 AND 120 MINUTES. THE AMOUNT OF SUPPLEMENTAL CARBON MATERIAL, E.G. ANTHRACTIC AND/OR OTHER MATERIAL, USED IN THE CARBON OR COKE MIXTURE DEPENDS UPON A NUMBER OF FACTORS, ESPECIALLY ITS ASH AND VOLATILE MATTER CONTENT AS WELL AS PRODUCT SPECIFICATIONS. IN ANY CASE, IT WILL NOT AMOUNT TO MORE THAN 90% OF THE CARBON AGGREGATE EMPLOYED AND MORE TYPICALLY WILL BE 75% OR LESS. BRIQUETS POSSESSING HIGH STRENGTH IN BOTH THEIR "GREEN" AND FINAL HEAT-TREATED STATES CAN BE PRODUCED EVEN WHILE EMPLOYING A RAPID FORMING OPERATION, I.E. ROLL BRIQUETTING
