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.
