Abstract:
1. A method of activating carbon comprising: a. providing a first material comprising carbon; b. providing a second material comprising an alkali compound; c. forming a mixture comprising the first material and second material, wherein the ratio of alkali compound to carbon comprises 1:1 or greater; d. heating the mixture in a reaction vessel to a reaction vessel temperature from about 500° C. to about 1200° C.; e. introducing water vapor into the reaction vessel when the reaction vessel temperature comprises a temperature greater than or equal to a first threshold temperature, wherein the first threshold temperature comprises about 200° C.; and f. discontinuing said introducing water vapor into the reaction vessel when the reaction vessel temperature comprises a temperature below a second threshold temperature, wherein the second threshold temperature comprises about 200° C.
