Abstract

A method for forming activated carbon from carbon feedstock involves forming particles of the carbon feedstock, introducing the carbon feedstock particles into a microwave reaction chamber and forming a fluidized bed of the particles within the chamber, introducing steam into the reaction chamber, and introducing microwaves into the reaction chamber to heat the particles using microwave energy and react the heated particles with the steam to form activated carbon.
