Also disclosed are methods of producing and using sorbent compositions of pelletized carbon products having higher strength and water resistance. Other embodiments include a system and method for removing contaminants from a process gas stream.
Claims32
A pelletized carbon composition, comprising:
- a powdered carbonaceous material, an organic binder, and a secondary binder.
A method of making pelletized carbon compositions, the method comprising:
- mixing a powdered carbonaceous material, an organic binder, a secondary binder, and water to form a mixture;
- extruding the mixture into pelletized structures;
- and
- drying the pelletized structures to form pelletized carbon compositions.
A pelletized carbon composition comprising:
- a powdered carbonaceous material;
- an organic binder;
- a secondary binder;
- sodium hydroxide and water;
- and
- wherein said sodium hydroxide and said water neutralize acidity of said powdered carbonaceous material thereby enabling said organic binder and said secondary binder to form a water-resistant bond.
A system for removing contaminants from a process gas stream, said contaminants including sulfur oxides, nitrogen oxides, and/or mercury (Hg) the system comprising:
- a source of the process gas stream;
- a pollutant control unit containing a pelletized carbon composition comprising a powdered carbonaceous material, an organic binder, and a secondary binder.
A method for removing contaminants from a process gas stream, said contaminants including sulfur oxides, nitrogen oxides, and/or mercury (Hg) the method comprising:
- providing a source of the process gas stream from an industrial unit including a boiler or incinerator;
- providing a pollutant control unit containing a pelletized carbon composition comprising a powdered carbonaceous material, an organic binder, and a secondary binder;
- treating the process gas stream by contact with the pelletized carbon composition;
- and
- subsequently removing said contaminants from the process gas stream.
