  • Patent number: 11905573
    Abstract: Novel methods of recovering neodymium and related rare earth elements from permanent magnets of various compositions are described. The methods employ processing steps including converting the magnet material to a higher surface area form such as a powder, treating the mixture with alkaline solutions to form product concentrated in neodymium and rare earth metals. Inexpensive materials such as ammonia, ammonium carbonate, carbon dioxide, water are recycled in a process that uses moderate temperatures, pressures and non-corrosive and environmentally-friendly chemicals.

  • Patent number: 9926245
    Abstract: Methods to synthesize fuels and chemicals from natural gas liquids are described. Higher alcohols are synthesized starting from natural gas liquid compounds by converting an alkane from a NGL to an olefin, dimerizing said olefin, and, hydrating said olefin product to form a higher alcohol. Higher alcohols are synthesized starting from natural gas liquid compounds by converting an alkane from a NGL to an olefin, oxidizing the olefin to form a ketone or aldehyde and, hydrogenating the aldehyde or ketone product to form a higher alcohol. Thus, NGL component butane may be dehydrogenated to form butane, butylene is oxidized in the presence of a catalyst to form methylethyl ketone and methylethyl ketone hydrogenated to form butanol.
