Abstract
The present invention relates to carbon nanocomposite sorbents. The present invention provides carbon nanocomposite sorbents, methods for making the same, and methods for separation of a pollutant from a gas that includes that pollutant. Various embodiments provide a method for reducing the mercury content of a mercury-containing gas.
Claims22
A method for reducing the pollutant content of a pollutant-containing gas, comprising:
- providing or obtaining a carbon nanocomposite sorbent material;
- providing or obtaining a halogen or halide promoter;
- promoting at least a portion of the sorbent material by chemically reacting the portion of the sorbent material with the halogen or halide promoter to form a promoted sorbent;
- contacting at least part of the promoted sorbent with the pollutant, to form a pollutant-sorbent composition;
- and
- separating at least some of the pollutant-sorbent composition from the pollutant-containing gas, to give a cleaned gas.
3 more elements
A method for reducing the mercury content of a mercury-containing gas, comprising:
- providing or obtaining a carbon nanocomposite sorbent, the carbon nanocomposite sorbent made by steps comprising
- providing or obtaining a carbon precursor;
- providing or obtaining a substrate material;
- contacting the carbon precursor and the substrate material, to provide a nanocomposite starting material;
- and
- heating the nanocomposite starting material, to provide the carbon nanocomposite sorbent;
- providing or obtaining a halogen or halide promoter;
- promoting at least a portion of the sorbent material by chemically reacting the portion of the sorbent material with the halogen or halide promoter to form a promoted sorbent;
- contacting at least part of the promoted sorbent with the mercury, to form a mercury-sorbent composition;
- and
- separating at least some of the mercury-sorbent composition from the pollutant-containing gas.
