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.

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.

Fuels and chemicals from lower alkanes

In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.
