Abstract
Adsorptive coke is made by heating a bituminous coal containing at least 5% oxygen of grain size up to 0.2 mm. in an inert atmosphere at a rate of several hundred degrees C. per minute to 600 DEG to 900 DEG C. without combustion, and allowing the heated coal to cool in an inert atmosphere. The oxygen content is preferably above 10%. If it is below 5% the content may be raised by heating in oxygen to 230 DEG C. for 8 to 72 hours. The bituminous coal is preferably heated to 600 DEG to 900 DEG C. for 1 to 10 minutes and cooling is preferably delayed for 5 to 10 minutes before being started. The starting material may be formed into briquettes before heating. The product may be used for the chlorination of water.ALSO:In the example sulphur dioxide is removed from air by contacting with active coke produced by flash pyrolysis of a powdered or briquetted bituminous coal containing at least 5% oxygen, without combustion in an inert atmosphere, the coke being subsequently cooled in an inert atmosphere.
