Abstract:
A method of producing a preconditioned ultra-low emission carbon material for purifying a contaminated reactive fluid, said method 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 an ultra-low emission carbon material is produced; e) purging the ultra-low emission carbon material with an ultra-purified reactive gas at room temperature for a specific period of time; f) heating the ultra-low emission carbon material under the ultra-purified reactive gas purge at a temperature range of about 50Â° to 400Â° C. for between a few hours and a few days, thereby producing a preconditioned ultra-low emission carbon material; and g) maintaining said preconditioned ultra-low emission carbon material in a substantially non-contaminating environment.
