Abstract: The present disclosure relates generally to methods and systems for achieving enhanced catalytic performance via the strategic arrangement of multiple catalyst beds in series, where each catalyst bed comprises a compositionally-distinct catalyst, and each catalyst facilitates the conversion of the same structural moieties on the reactant to form the same product. Arranging multiple catalyst beds according to the methods and systems disclosed herein allows a predictable enhancement of conversion of the reactant to product without the need for time-consuming experimentation to test all possible catalysts configurations.

Abstract: The present disclosure relates generally to processes and systems for the hydrodeoxygenation of an oxygenate feedstock that increases the conversion of oxygenates to hydrocarbons while avoiding detrimental effects resulting from increasing the severity of the hydrodeoxygenation reaction.

Abstract: Carbohydrates as derived from plant biomass can be converted into mono-alcohols, diols, and/or bi-functional alcohols or into carboxylic acid derivatives. By catalytic transesterification of such carbohydrate derivatives, ester-type diesel-fuel blendstock components may be produced. More specifically, alkyl levulinates are catalytically trans-esterified with hydroxyl-functionalized compounds where both the alcohols and the alkyl levulinates are derived from biomass carbohydrates. Esters produced in this way show physicochemical characteristics that make them suitable for use as diesel fuel blendstock.

Abstract: Integrating a biomass pyrolysis and upgrading process into a fluid catalytic cracking unit. The process uses conventional FCC feed and a mixture of a solvent and biomass to produce upgraded fuel products. A slurry stream composed of solid biomass particles and a solvent is fed into an FCC riser through a slurry pump to achieve biomass pyrolysis and in situ pyrolysis oil upgrading. The catalytic cracking of the conventional petroleum feed also occurs in the riser.

Abstract: A biomass pyrolysis product is quenched by direct cooling with a cold quench fluid and initial product separation is performed based on boiling point and solubility in the quench fluid. A properly chosen quench fluid may act as a selective solvent, thus providing dilution of unstable precursors of pyrolytic lignin or other heavy by-products, and/or separation of certain undesirable pyrolysis oil components such as water and light acids.

Abstract: A process for converting biomass to hydrocarbons and oxygenates that may include providing a biomass feedstock and de-oxygenating the biomass feedstock to form a solid-intermediate. The process may further include liquefaction of the solid intermediate, which may be carried out either by rapid heating followed by condensation or by liquefying by applying high pressure. The liquefaction of the solid intermediate may produce a mixture of hydrocarbons and oxygenates, which is generally termed as biocrude. Further, the biocrude is processed by one or more refining means for production of hydrocarbons that can be used as fuel.

Abstract: The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting biomass to condensable vapor intermediates such as pyrolysis oil by means of catalytic pyrolysis in a reactor comprising at least one auger, where the catalyst also comprises a heat carrier. The intermediates produced may be further processed for production of renewable hydrocarbon fuels.

Abstract: The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting algal biomass to condensable vapor intermediates such as pyrolysis oil by means of pyrolysis in a reactor comprising at least one auger. The intermediates may be further processed for production of renewable hydrocarbon fuels. The disclosed processes assist in preventing premature devolatization of algal biomass during pyrolysis, thereby increasing efficiency and commercial feasibility.

Abstract: A single pass direct conversion of biomass derived oxygenates to longer chain hydrocarbons is described. The longer chain hydrocarbons include higher naphthene content which is quite useful in the distillate range fuels or more particularly, the jet and diesel range fuels. Naphthenes help the biomass derived hydrocarbons meet product specifications for jet and diesel while really helping cold flow properties.
