Abstract
A fiber bundle contactor may include: a flow path defined by a conduit; a catalytic carbon fiber bundle disposed in the conduit; and an inlet allowing fluid flow into the flow path. A method may include: introducing into vessel a hydrocarbon comprising mercaptan sulfur, an aqueous caustic solution, and an oxidizer; reacting at least a portion of the mercaptan sulfur and the aqueous caustic solution to produce a mercaptide; and reacting the mercaptide and the oxidizer in the presence of a catalytic carbon fiber bundle to produce a disulfide oil.
Claims18
A fiber bundle contactor comprising:
- a flow path defined by a conduit;
- a catalytic carbon fiber bundle disposed in the conduit;
- and
- an inlet allowing fluid flow into the flow path,
- wherein the catalytic carbon fiber bundle comprises a carbon fiber, an amine compound covalently bonded to the carbon fiber, and an organometallic macrocycle covalently bonded to the amine compound.
A method comprising:
- introducing into a fiber bundle contactor a hydrocarbon comprising mercaptan sulfur, an aqueous caustic solution, and an oxidizer, wherein the fiber bundle contactor comprises a flow path defined by a conduit, a catalytic carbon fiber bundle disposed in the conduit, and an inlet allowing fluid flow into the flow path, wherein the catalytic carbon fiber bundle comprises a carbon fiber, an amine compound covalently bonded to the carbon fiber, and an organometallic macrocycle covalently bonded to the amine compound;
- reacting at least a portion of the mercaptan sulfur and the aqueous caustic solution to produce a mercaptide;
- and
- reacting the mercaptide and the oxidizer in the presence of the catalytic carbon fiber bundle to produce a disulfide oil.
A method comprising:
- introducing into a fiber bundle contactor an aqueous solution comprising a mercaptide and an oxidizer, wherein the fiber bundle contactor comprises a flow path defined by a conduit, a catalytic carbon fiber bundle disposed in the conduit and, an inlet allowing fluid flow into the flow path, wherein the catalytic carbon fiber bundle comprises a carbon fiber, an amine compound covalently bonded to the carbon fiber, and an organometallic macrocycle covalently bonded to the amine compound;
- and
- reacting the mercaptide and the oxidizer in the presence of the catalytic carbon fiber bundle to produce an aqueous caustic solution.
