    摘要： Methods are provided for producing low oxygen biomass-derived pyrolysis oil from carbonaceous biomass feedstock. The carbonaceous biomass feedstock is pyrolyzed in the presence of a steam reforming catalyst to produce char and pyrolysis gases. During pyrolysis, a portion of the oxygenated hydrocarbons in the pyrolysis gases is converted into hydrocarbons by steam reforming also yielding carbon oxides and hydrogen gas. The hydrogen gas at least partially deoxygenates a residual portion of the oxygenated hydrocarbons. Additional hydrogen gas may also be produced by water-gas shift reactions to deoxygenate the residual portion of the oxygenated hydrocarbons in the pyrolysis gases. Deoxygenation may occur in the presence of a hydroprocessing catalyst. A condensable portion of the pyrolysis gases is condensed to form low oxygen biomass-derived pyrolysis oil.

    摘要： A solid terephthalic acid composition and a process for producing terephthalic acid from para-xylene. The process comprises forming a mixture comprising the para-xylene, a solvent, a bromine source, and a catalyst; and oxidizing the para-xylene by contacting the mixture with an oxidizing agent at oxidizing conditions to produce a solid oxidation product comprising terephthalic acid, para-toluic acid, 4-carboxybenzaldehyde. The solvent comprises a carboxylic acid having from 1 to 7 carbon atoms and an dialkyl imidazolium ionic liquid; and the catalyst comprises at least one of cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, and zirconium. The solid terephthalic acid composition comprises, less than about 4,000 ppm-wt 4-carboxybenzaldehyde content, and more than about 2,000 ppm-wt a para-toluic acid.

    摘要： Methods are provided for producing low oxygen biomass-derived pyrolysis oil from carbonaceous biomass feedstock. In an embodiment, hydrogen gas is produced in the presence of a low temperature reforming catalyst from hemicellulose extracted from the carbonaceous biomass feedstock. The carbonaceous biomass feedstock, both whole and hemicellulose-depleted, is pyrolyzed in the presence of a pyrolysis upgrading catalyst to produce char and pyrolysis gases comprising oxygenated hydrocarbons and steam. A portion of the oxygenated hydrocarbons are converted into hydrocarbons. A residual portion of the oxygenated hydrocarbons of the pyrolysis gases is deoxygenated with the hydrogen and optionally, additional hydrogen gas. A condensable portion of the pyrolysis gases is condensed into low oxygen biomass-derived pyrolysis oil.

    摘要： A process for the production of methanol from methane has been developed. The process involves reacting methane with an oxidant such as oxygen or a peroxide in the presence of a catalyst and a solvent in a reaction zone to produce an effluent stream comprising a methanol product. The effluent stream is next separated into a gaseous stream comprising unreacted methane and carbon dioxide and a liquid stream comprising the methanol product and solvent. Next the gaseous stream is further separated to provide a methane stream which is recycled to the reaction zone. Finally, a methanol stream is isolated and a solvent stream is recycled to the reaction zone.
