Abstract
A method and system for making enhanced activated carbon are disclosed. A first heated gas including oxygen flows through a fluidized bed including particles comprising activated carbon to form oxidized activated carbon particles. A second heated gas including nitrogen, ammonia or a combination thereof, flows through a fluidized bed including the oxidized activated carbon particles to form nitrogenated activated carbon particles. A third heated gas including hydrogen flows through a fluidized bed including the nitrogenated activated carbon particles to form the enhanced activated carbon particles.
