摘要： A process is disclosed for the production of refinery transportation fuel or components for refinery blending of transportation fuels having a reduced amount of sulfur and/or nitrogen-containing impurities. The process involves contacting a hydrocarbon feedstock containing the above impurities with an immiscible phase containing hydrogen peroxide and acetic acid in an oxidation zone to selectively oxidize the impurities. After a gravity phase separation, the hydrocarbon phase containing any remaining oxidized impurities, is passed to an extraction zone wherein aqueous acetic acid is used to extract a portion of any remaining oxidized impurities. A hydrocarbon stream having reduced impurities can then be recovered. The acetic acid phase effluents from the oxidation and the extraction zones can then be passed to a common separation zone for recovery of the acetic acid and for optional recycle back to the oxidation and extraction zones.

摘要： Acetyl anhydrides such as acetyl sulfate are produced by a process for comprising contacting methane and carbon dioxide in an anhydrous environment in the presence of effective amounts of a transition metal catalyst and a reaction promoter, and an acid anhydride compound, and optionally an acid. The acetyl anhydride can be contacted with water to produce acetic acid or with an alcohol to produce a product comprising an acetate ester and that may also comprise acetic acid. Optionally, water in stoichiometric amounts or less, with respect to the acetic anhydride, may be fed to a continuous process of this type to produce some acetic acid in situ.

摘要： A process for the production of acetic acid which comprises carbonylating methanol and/or a reactive derivative thereof in one or more reactors in a liquid reaction composition comprising iridium carbonylation catalyst, ruthenium promoter, methyl iodide co-catalyst, methyl acetate, acetic acid and water. The liquid reaction composition from the one or more reactors is passed to one or more flash separation stages to form (i) a vapour fraction comprising condensable components and a low pressure off-gas comprising carbon monoxide and (ii) a liquid fraction comprising iridium carbonylation catalyst, ruthenium promoter and acetic acid solvent. The condensable components are separated from the low pressure off-gas. The concentration of carbon monoxide in the low pressure off-gas is maintained according to the formula: Y>mX+C wherein Y is the molar concentration of carbon monoxide in the low pressure off-gas, X is the concentration in ppm by weight of ruthenium in the liquid reaction composition, m is about 0.012 and C is about −8.7.
