  • Process for the production of activated coke for simultaneous desulfurization and denitrification
    Patent number: 5840651
    Abstract: Disclosed is a process for the production of high-strength activated coke for desulfurization and denitrification. The process comprises forming a mixture of plural coals of different caking properties and a binder, said mixture containing said coal of higher caking property in an amount of 10-50 wt. %, subjecting the thus-formed mixture to oxidization treatment in an atmosphere having an oxygen concentration of 1-18 vol. % and a temperature of 50.degree.-250.degree. C., subjecting the thus-treated mixture to carbonization treatment under conditions of an oxygen concentration not higher than 8 vol. %, a heating efficiency of 10.degree.-50.degree. C./min and a final temperature 600.degree.-900.degree. C., and then subjecting again the thus-carbonized mixture to oxidation treatment at an oxygen concentration of 3-18 vol. % and a temperature of 200.degree.-600.degree. C.
