IMPROVED BROMINATED SORBENTS FOR REMOVING MERCURY FROM EMISSIONS PRODUCED DURING FUEL COMBUSTION

摘要

Activated cellulosic based carbon is rendered more thermally stable by exposure to water or aqueous acid and optionally to a halogen and/or a halogen containing compound. Such treated cellulosic based carbon has enhanced thermal properties and is suitable for use in mitigating the content of hazardous substances in flue gases especially flue gases having a temperature within the range of from about 100 �C to about 420 �C.
