Abstract
Recovery of spent active carbon particles. N6A. By (a) forming a dispersion of it in an activating carrier gas; (b) heating the dispersion to 732-954 degrees C forfromless than 1 sec. to about 5 sec., while maintaining a wt./vol. ratio of carbon to carrier gas of 0.0016 to 1.6 kg/m3; (c) cooling the dispersion. Pref. the activated carrier gas is steam, and the temp. range is 816-871 degrees C. The dispersion is formed from an aqueous slurry of the spent carton, and the steam is produced by evaporation of the water in the slurry.
