  • Publication number: 20110146141
    Abstract: Low metal, low water biomass-derived pyrolysis oils and methods for producing the same are provided. Metal- and water-containing biomass-derived pyrolysis oil is contacted with an acidic ion-exchange resin having sulfonic acid groups to produce a low metal, water-containing biomass-derived pyrolysis oil. The low metal, water-containing biomass-derived pyrolysis oil is removed from the spent ion-exchange resin after ion-exchange. The low metal, water-containing biomass-derived pyrolysis oil is distilled to produce a low metal, low water biomass-derived pyrolysis oil and a distillation product. The distillation product comprises one or both of an alcohol ion-exchange regenerant and an acidic ion-exchange regenerant which may be used to regenerate the spent ion-exchange resin. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.

  • Publication number: 20110146145
    Abstract: Methods for regenerating acidic ion-exchange resins and reusing regenerants in such methods are provided. A spent ion-exchange resin is contacted with an alcohol ion-exchange regenerant. The spent ion-exchange resin is thereafter contacted with an acidic ion-exchange regenerant to recharge the acidic ion-exchange resin to produce a regenerated acidic ion-exchange resin. Metal- and water-containing biomass-derived pyrolysis oil is then contacted with the regenerated acidic ion-exchange resin to produce low metal, water-containing biomass-derived pyrolysis oil. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.

  • Publication number: 20100331568
    Abstract: Catalytic processes for the conversion of 2,5-dimethyl furan (DMF) to para-xylene are described. Para-xylene is a key product that is currently obtained commercially from petroleum sources. However, it has now been determined that the cycloaddition of ethylene to DMF provides an alternative route to para-xylene. Advantageously, the DMF starting material for the processes may be synthesized from carbohydrates (e.g., glucose or fructose), thereby providing a pathway that relies at least partly, if not completely, on renewable feedstocks.

  • Publication number: 20090283442
    Abstract: A hydrocarbon product stream having hydrocarbons with boiling points in the aviation fuel range is produced from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating, deoxygenating, isomerization, and selectively hydrocracking the feedstock to produce paraffinic hydrocarbons having from about 9 to about 16 carbon atoms and a high iso/normal ratio in a single reaction zone containing a multifunctional catalyst, or set of catalysts, having hydrogenation, deoxygenation, isomerization and selective hydrocracking functions.

  • Publication number: 20090287029
    Abstract: A process for controlling the concurrent production of both diesel range hydrocarbons and aviation range hydrocarbons from renewable feedstocks such as plant oils and animal oils. The process involves determining the required specification of the desired products and the desired relative yields of the product that still meet the required specifications. The necessary isomerization and selective hydrocracking zone conditions are determined in order to create a mixture of paraffins which meet the required product specifications and yields. The necessary fractionation zone conditions are determined to separate the desired products.

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.

  • Patent number: 7288684
    Abstract: 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.
