- 24 - ABSTRACT This invention relates to a production process of formed activated coke for SOx and NOx removal which is employed in treatment systems for various flue gases and the like. The formed activated coke for SOx and NOx removal obtained in accordance with the process of this inven- tion has excellent pressure resistance, abrasion resistance and impact strength and also superb SOx- and NOx-removing ability, so that the coke is suitable for use in moving-bed, SOx and NOx- removing systems. The formed activated coke for SOx and NOx removal can of course show excellent SOx- and NOx-removing ef- fects when employed in conventional SOx- and NOx- removing processes and, moreover, owing to its charac- teristic high NOx-removing ability, is suited for the removal of NOx from low-SOx flue gas of a fluidized-bed combustion boiler or cogeneration power plant. According to the process of this invention, dried, formed activated coke prepared from coal as a raw material is reacted with SO3 gas at 100-300°C, fol- lowed by heat treatment at 300-600°C in an inert atmo- sphere.
