Abstract
Catalytic systems and methods for treating process streams are disclosed. Catalytic wet oxidation and hydrolysis techniques may be used to treat one or more undesirable constituents. Methane may be produced in connection with at least some embodiments.
Claims20
A method of producing methane comprising:
- contacting an aqueous fluid comprising at least one undesirable constituent with a heterogeneous catalyst at a pressure from about 20 atm to about 240 atm and a temperature from about 150° C. to about 373° C. to hydrolysize the at least one undesirable constituent in the fluid and generate an amount of methane,
- wherein the heterogeneous catalyst comprises a member selected from the group consisting of ruthenium, nickel, cobalt, iron, and combinations thereof, and a solid support selected from the group consisting of alumina, silica, and a carbide.
The process of claim 3, wherein the temperature is from about 200° C. to about 260° C.
A method of producing methane comprising:
- introducing a produced water comprising a chemical oxygen demand to a treatment vessel;
- subjecting the produced water to a pressure from about 20 atm to about 240 atm in or upstream of the treatment vessel;
- subjecting the produced water to a temperature from about 150° C. to about 373° C. in or upstream of the treatment vessel;
- introducing a heterogeneous catalyst to the produced water in or upstream of the treatment vessel to promote methane formation, wherein the heterogeneous catalyst comprises a member selected from the group consisting of ruthenium, nickel, cobalt, iron, and combinations thereof, and a solid support selected from the group consisting of alumina, silica, and a carbide;
- and
- capturing the formed methane.
3 more elements
A method of producing methane comprising:
- subjecting an aqueous fluid comprising at least one undesirable constituent to catalytic conditions effective to hydrolysize the at least one undesirable constituent in the fluid and generate an amount of methane.
