Abstract: An iridium-based catalyst and method of making the catalyst are described. The catalyst comprises a catalytic material comprising iridium oxide or a mixture of iridium and iridium oxide nanoplates. It may have a BET surface area of at least 50 m2/g and a pore volume of at least 0.10 cc/g. The nanoplates are less than 50 nm thick. The catalyst is made using organic and inorganic structure directing agents.

Abstract: A process is provided of treating a feed comprising polyethylene terephthalate comprising dissolving said feed in a polar solvent at a temperature between about 100 to 250° C. to produce a dissolved feed; then adding an anti-solvent that is less polar than said polar solvent followed by cooling a resulting mixture resulting in precipitation of purified polyethylene terephthalate and then separation of solid purified polyethylene terephthalate from remaining liquids.

Abstract: A catalyst composition comprising a support comprising a mixture of amorphous silica-alumina and non-zeolitic alumina comprising no more than 75 wt % amorphous silica-alumina and having a ratio of moles of silicon to moles of aluminum in the range of about 0.05 to about 0.50. A first hydrogenation metal comprising platinum, a second hydrogenation metal from Group VIIB or Group VIII of the Periodic Table other than platinum and an optional third metal from Group IA of the Periodic Table may be deposited on the support. The ratio of moles of silicon to the moles of the first hydrogenation metal, the second hydrogenation metal and the optional third metal on the support may be between about 15 and about 75.

Abstract: Processes for removing sulfur and nitrogen contaminants from hydrocarbon streams are described. The processes include contacting the hydrocarbon stream comprising the contaminant with lean halometallate ionic liquid an organohalide resulting in a mixture comprising the hydrocarbon and rich halometallate ionic liquid comprising the contaminant. The mixture is separated to produce a hydrocarbon effluent and a rich halometallate ionic liquid effluent comprising the rich halometallate ionic liquid comprising the contaminant.

Abstract: Processes for removing sulfur and nitrogen contaminants from hydrocarbon streams are described. The processes include contacting the hydrocarbon stream comprising the contaminant with lean carbenium pseudo ionic liquid or a combination of carbenium pseudo ionic liquid and ionic liquid to produce a mixture comprising the hydrocarbon and rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid comprising the contaminant.

Abstract: A process for the selective oxidation of methane to methanol using a supported transition metal catalyst has been developed. Examples of the transition metals which can be used are copper and palladium, while an example of a support is silica. Optionally, the catalyst can contain a modifier component such as cesium. Generally the process involves contacting a gas stream, comprising methane, a solvent such as trifluoroacetic acid and an oxidizing agent such as air or hydrogen peroxide with the catalyst, at oxidation conditions to produce a methyl ester, e.g. methyl trifluoroacetate. Finally, the methyl ester is hydrolyzed to yield a methanol product stream.
