    Abstract: 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.

    Abstract: A catalytic process for generating at least one polyol from a feedstock comprising cellulose is performed in a continuous manner. The process involves, contacting, continuously, hydrogen, water, and a feedstock comprising cellulose, with a catalyst to generate an effluent stream comprising at least one polyol, water, hydrogen, and at least one co-product. The water, hydrogen, and at least one co-product are separated from the effluent stream and recycled to the reaction zone. The polyol is recovered from the effluent stream.

    Abstract: Low oxygen biomass-derived pyrolysis oils and methods for producing them from carbonaceous biomass feedstock are provided. The carbonaceous biomass feedstock is pyrolyzed in the presence of a catalyst comprising base metal-based catalysts, noble metal-based catalysts, treated zeolitic catalysts, or combinations thereof to produce pyrolysis gases. During pyrolysis, the catalyst catalyzes a deoxygenation reaction whereby at least a portion of the oxygenated hydrocarbons in the pyrolysis gases are converted into hydrocarbons. The oxygen is removed as carbon oxides and water. A condensable portion (the vapors) of the pyrolysis gases is condensed to low oxygen biomass-derived pyrolysis oil.

    Abstract: A catalytic composite of a refractory inorganic oxide whose bound surface hydroxyl group has reacted with a Friedel-Crafts type metal halide and whose acidity has been modified by the deposition of a monovalent metal cation, especially an alkali metal cation, or alkaline earth metal cation shows superior selectivity and a significantly decreased cracking tendency relative to similar catalysts without the monovalent metal or alkaline earth metal cation. The resulting alkylate from an isobutane-butene feedstock shows a substantial increase in research octane number relative to the alkylate formed by a similar catalyst which has not been so modified by an alkali or alkaline earth metal cation.
