ABSTRACT:
An improved apparatus and method for the manufacture of activated carbon wherein a carbonaceous raw material impregnated with a chemical activating agent is treated by controlling the rate of heat transfer to the particles via indirect heating of the activation furnace and simultaneously introducing a flow of independently controlled sweep gas at spaced intervals along the path of travel of the particles through the furnace to more precisely control the activation reaction and the level of densification of the particles during certain stages of treatment. In a more preferred embodiment, the particles are processed in a plurality of treatment stages related to the rate of evolution of water and/or the evolution of water and the chemical activating agent and the rates of heat transfer and the volume flow rate of sweep gas are closely controlled relative to achieving predetermined levels of densification of the particles during each treatment stage and selected levels of activation properties in the end product.
