    摘要: An integrated coal pretreatment, liquefaction and gasification process is provided in which particulate coal is contacted with a vapor phase hydrogen donor solvent to swell the coal particles. The swollen coal particles are subjected to coal liquefaction conditions at relatively low temperatures. The solid residue of the coal liquefaction stage is subjected to pyrolysis conditions at relatively high temperatures to produce an additional amount of hydrocarbonaceous oil. The solid residue of the pyrolysis stage is gasified by treatment with steam and a molecular oxygen-containing gas to produce a hydrogen-containing gas.

    摘要: Phenol-containing streams are treated by an oxygen-alkylation process to convert substantially all of the phenol groups to ether groups. The oxygen-alkylation process comprises contacting the phenol-containing stream, preferably a coal liquid, with (a) a basic solution comprising one or more oxides or hydroxides of a metal selected from the group consisting of alkali and alkaline-earth metals; and (b) an alkylating agent represented by the formula RX where R is a C.sub.1 to C.sub.18 alkyl, allyl, cycloalkyl, haloalkyl, benzyl or arylalkyl group provided X is located on the alkyl portion of the compound and X is sulfate or a halide selected from the group consisting of chlorine, bromine and iodine.

    摘要: Disclosed is a process for the production of esters. In particular, the process includes contacting an olefin or an ether with carbon monoxide and an acid composition comprising BF3.2CH3OH to from a product composition, adding an alcohol to the product composition, and separating the BF3.2CH3OH from the ester. The separated BF3.2CH3OH may then be recycled to the reaction unit.

    摘要: Disclosed is a method for enhancing the conversion of carbonous materials, such as coal and oil shale. The method comprises converting the carbonous material in the presence of a vapor phase hydrogen donor material containing 1 or more hydrogen donor solvents wherein each donor material is characterized by: (a) a heterocyclic ring in which the heteroatom is nitrogen, (b) having at least one donatable hydrogen located on the heterocyclic ring, and (c) becoming more unsaturated and/or aromatic upon the loss of the donatable hydrogen(s). The conversion is performed at substantially atmospheric pressure, at an effective vapor residence time and at a temperature from about the boiling point of the hydrogen donor material to about 550.degree. C.
