ACTIVATED CARBON SORBENT INCLUDING NITROGEN AND METHODS OF USING THE SAME

摘要

The present invention relates to activated carbon sorbents including nitrogen. In various embodiments, the present invention provides an activated carbon sorbent including a halogen- or halide-promoted activated carbon, the activated carbon sorbent particles including nitrogen in a surface layer of the sorbent particles. In various embodiments, the present invention provides a method of reducing the pollutant content in a pollutant-containing gas using the activated carbon sorbent. In various embodiments, the activated carbon sorbent can remove mercury from a mercury-containing gas that includes sulfur(VI) such as SO3 more efficiently than other sorbents.

主权项

1. A method of reducing the pollutant content in a pollutant-containing gas, the method comprising:
obtaining or providing an activated carbon sorbent comprising activated carbon sorbent particles comprising nitrogen in a surface layer of the sorbent particles; contacting a pollutant-containing gas with the activated carbon sorbent, to form a pollutant-sorbent composition; and separating at least some of the pollutant-sorbent composition from the pollutant-containing gas, to give a separated gas.
