Abstract:
The present invention relates to acrylic block polymers, either block copolymers or homopolymers, synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in bio-derived fuel compositions. They are especially useful in modifying the low temperature flow behavior in bio-derived fuels. The acrylic polymers are especially useful as cold filter plugging control additives in bio-derived fuels.
Abstract:
Lignocellulosic biomass hydrolysate fermentation broth may be processed to produce a high solids syrup having relatively low viscosity that has a high energy content and may be burned in a fermentation production process. The high solids syrup was achieved through liquid/solid separation of broth or depleted broth producing a thin stillage with low suspended solids allowing evaporation to high solids while maintaining low viscosity.
Abstract:
Methods, process, apparatus, equipment, and systems are disclosed for converting biomass into bio-oil fractions for chemicals, materials, feedstocks and fuels using a low-cost, integrated fast pyrolysis system. The system improves upon prior art by creating stable, bio-oil fractions which have unique properties that make them individually superior to conventional bio-oil. The invention enables water and low-molecular weight compounds to be separated into a final value-added fraction suitable for upgrading or extracting into value-added chemicals, fuels and water. Initial bio-oil fractions from the process are chemically distinct, have low-water content and acidity which reduces processing costs normally associated with conventional bio-oil post-production upgrading since fewer separation steps, milder processing conditions and lower auxiliary inputs are required. Biochar is stabilized so that it can be handled safely. The integrated fast pyrolysis process includes biomass storage, preparation, pretreatment, and conversion, product recovery and processing to create and store stable biochar and bio-oil fractions.

The invention relates to the use of steam cracked tar with the bottoms product of a flash drum integrated with a pyrolysis furnace. In embodiments, the steam cracked tar is added to fuel oil.
Abstract:
An aviation gasoline (Avgas) formulation free from tetraethyl lead (TEL) for piston driven aircraft is described, the formulation comprising, in volume percent, between 0 and 65.2 base alkylate, between 0 and 50 super-alkylate, between 0 and 25 toluene, between 2 and 10 of a toluidine isomer blend, between 0 and 5 ethyl alcohol, between 0 and 25 C5 cut and between 0 and 10 triptane. The formulations are prepared by admixing the components, with the order of mixing being from the denser to the less dense, except in the case of the toluidine isomer blend, which in spite of being the denser product is the latest to be added to the other streams in order to by-pass homogenization problems.
Abstract:
A method is disclosed for reducing the freezing point of unleaded aminated aviation gasoline to −58° C. or lower by the addition of tert-amylphenylamine.
Abstract:
Slurry fuels and associated methods are disclosed herein. One aspect of the invention is directed toward a slurry fuel that includes a liquid hydrocarbon based fuel suitable for use in an air-breathing power plant, metallic particles (e.g., boron), and a fluoropolymer (e.g., polytetrafluoroethylene). In selected embodiments the slurry fuel can further include a surfactant (e.g., polyolefin amide alkeneamine and/or Product NB463S84 produced by GE Betz, Inc.). Other aspects of the invention are directed toward a slurry fuel that includes a liquid hydrocarbon based fuel, metallic particles, and a surfactant having a composition that lowers the surface tension of the liquid hydrocarbon based fuel and reduces the tendency for the metallic particles to separate from the liquid hydrocarbon based fuel.
Abstract:
A method for manufacturing a fuel oil includes making a fuel, conveying the fuel to a storage tank, providing a liquid and a modified fuel additive, and mixing the fuel, the liquid and the modified fuel additive to form a product of an environmental protection fuel oil. The fuel and the hydrogen and oxygen contained in the liquid are modified by the modified fuel additive so that the fuel and the hydrogen and oxygen contained in the liquid are dissolved completely. Thus, the environmental protection fuel oil only contains the fuel having a determined rate to reach the same burning efficiency, thereby saving the fuel and price.
Abstract:
Disclosed herein is a fuel composition for internal combustion engines comprising a trialkylamine. Specifically, the fuel composition for internal combustion engines is prepared by adding a tertiary amine of trialkylamine to a gasohol which is a mixture of anhydrous or hydrous ethanol and naphtha, wherein the hydrous ethanol contains up to 10% by volume of water and shows an improved inhibition of a phase separation and corrosion.
Abstract:
A fuel, a composition and a method are provided for fueling an engine with the fuel. The fuel, the composition and the method have an additive mixed with a base and combusted in the engine. The additive may be, for example, an oil, an extract, and/or a fuel composition. The base may be, for example, a petroleum-based fuel, a vegetable oil-based fuel, a biomass-based fuel, a biodiesel-based fuel and/or an animal fat-based fuel. Additionally, the fuel, the composition, and the method release an agent during combustion of the fuel. The agent may be, for example, a molecule, a gas, a particle and/or a liquid. Moreover, the agent produces an effect, such as, for example, a chemical effect, an aromatic effect, an anti-bacterial effect, an anti-viral effect, an anti-fungal effect, and/or an antimicrobial effect. The additive lowers viscosity of the fuel and/or the composition to prevent gelling of the fuel and/or the composition. The additive increases an amount of heat generated by combustion of the fuel and/or the composition to prevent gelling of the fuel and/or the composition.
