Abstract:
A process of producing an ultra-low emission carbon material comprising:a) placing a carbon material containing trace amounts of water in a reactor having a gas inlet and a gas outlet; b) heating said carbon material in said reactor for at least twenty four hours at a temperature between about 300Â° C. and 800Â° C. under a flow of ultra-dry inert gas; c) measuring the amount of water in said inert gas exiting said reactor; d) terminating said heating when the concentration of water in said inert gas exiting said reactor is below about ten parts-per-million, whereby said ultra-low emission carbon material is produced; and e) maintaining said ultra-low emission carbon material in a substantially non-contaminating environment.
