Abstract:
A method of producing an activated carbon, comprising selecting a raw material for direct-activation, applying a solution of at least 50% phosphoric acid by weight at a ratio of from 0.01 pounds to 0.3 pounds of phosphoric acid solution per pound to the raw material selected for direct activation to produce a phosphoric acid treated raw material, and direct-activating the phosphoric acid treated raw material via a gas activation process to produce an activated carbon.
