Abstract
Embodiments of an organosulfur capture or scavenger nanomaterial of this disclosure include a sorbent containing a composition of a mixed metal oxide, the metal being in various oxidation states. In embodiments, the mixed metal is manganese, iron, nickel, copper, or zinc. In some embodiments the sorbent includes a first mixed metal oxide and a second different metal or mixed metal oxide. The scavenger material may be synthesized from a metal precursor salt, neutralized and dried, and then washed or soaked to remove one or more byproducts. The resulting sorbent is in nanoparticulate form and has an amorphous non-crystalline structure.

A method for removing organosulfur from a liquid hydrocarbon stream, the method comprising:
- passing a liquid hydrocarbon process stream through a vessel containing a non-magnetic mixed metal oxide, hydroxide, and oxyhydroxide sorbent nanomaterial, the metal being in at least;
- the non-magnetic mixed metal oxide, hydroxide, and oxyhydroxide sorbent nanomaterial having an amorphous non-crystalline structure and containing a metal in at least two oxidation states;
- the liquid hydrocarbon process stream having a first organosulfur content when entering the vessel and a second lower organosulfur content when exiting the vessel.
An organosulfur capture material for use in treating a liquid hydrocarbon stream, the organosulfur capture material comprising:
- a non-magnetic mixed metal oxide, hydroxide, and oxyhydroxide sorbent nanomaterial containing a metal oxide in at least two oxidation states;
- the non-magnetic mixed metal oxide, hydroxide, and oxyhydroxide sorbent nanomaterial having an amorphous non-crystalline structure and containing a metal in at least two oxidation states;
