4results about "Cobalt carbonyls" patented technology

This invention relates to the production of nickel tetracarbonyl and cobalt tricarbonyl nitrosyl from mixed metal hydroxide precipitate (MHP) comprising nickel, cobalt, and manganese.

Methods and reactor systems are provided for extracting metals, such as nickel, cobalt, and iron, from reduced, activated metal compounds (“feed materials”). Feed materials may be derived from mixed hydroxide precipitate. Feed materials and carbon monoxide gas are delivered into an extraction reactor of a reactor system, such as a shell tube heat exchanger. A flow path therein directs the feed material downward and the carbon monoxide gas upward, enabling contact therebetween, forming at least one metal carbonyl gas and a solid residue therein. The flow path further directs the upward flow of metal carbonyl gases, and the downward flow of the residue. Methods and reactor systems may further purge the residue: using nitric oxide to convert any remaining dicobalt octacarbonyl therein to cobalt tricarbonyl nitrosyl gas; using an inert gas to removing any cobalt tricarbonyl nitrosyl therein; and using an inert gas-oxygen mixture, to form a passivated residue.

This invention relates to the recovery of nickel and cobalt from lithium ion battery materials comprising nickel, cobalt, and manganese, such as cathode active materials (CAM) and / or black mass (BM) derived from battery materials.

The present disclosure relates to the production of nickel tetracarbonyl and cobalt tetracarbonyl hydride from mixed metal hydroxide precipitate (MHP) comprising nickel, cobalt, and manganese.
