    Abstract: Compositions and methods for forming hydrocarbon products from triglycerides are described. In one aspect, the methods involve the thermal decomposition of fatty acids, which can be derived from the hydrolysis of triglycerides. The thermal decomposition products can be combined with low molecular weight olefins, such as Fischer-Tropsch synthesis products, and subjected to molecular averaging reactions. Alternatively, the products can be subjected to hydrocracking reactions, isomerization reactions, and the like. The products can be isolated in the gasoline, jet and/or diesel fuel ranges. Thus, vegetable oils and/or animal fats can be converted using water, catalysts, and heat, into conventional products in the gasoline, jet and/or diesel fuel ranges.

  • Patent number: 8829258
    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.

  • Patent number: 8809606
    Abstract: Methods and apparatus for processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency are disclosed. In particular, multi-stage processes are disclosed to convert various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. Disclosed processes subject the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. Also disclosed are apparatus for performing multi-stage processes of converting waste products into useful materials, and at least one oil product that arises from the process.

  • Patent number: 8809605
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A process was designed to reduce the coke by co-feeding sugars/sugar derivatives with a saturated recycle stream containing hydrogenated products.

  • Patent number: 8802905
    Abstract: A unique, integrated non-obvious pathway to convert biomass to biofuels using integration of chemical processes is described herein. The present invention is simple, direct, and provides for the shortest or minimum path between biomass and transportation fuels with alcohols as intermediates, while avoiding hydrogen use during processing. Furthermore, the present invention allows the manufacture of “drop-in” substitutable fuels to be used as-is without modifications instead of conventional petroleum based fuels. The processing described herein is done under mild conditions, under relatively low pressures and temperatures, and under non-corrosive conditions obviating use of special equipment or materials.

  • Patent number: 8796494
    Abstract: A method of catalytically preparing a fluid product from solid carbonaceous material is described. In the method, at least one of the following equilibria is established by one or more catalysts: a) CH3OH=CO+2H2, b) CO+H2O=CO2+H2. In some versions, the solid carbonaceous material is woody biomass. Components of the fluid product can include one or a combination of C5-C9 alcohols. In certain versions, the method can be practiced with substantially all of the carbon in the carbonaceous material being converted to the fluid product. Also, in some versions, the fluid product can be prepared with substantially no char formation. The fluid product of various versions can be used directly as fuel or as a reagent for preparing commodity chemicals without the need for separating the fluid product components.
