Abstract:
The invention relates to a process for upgrading pyrolysis tar in the presence of a utility fluid. The utility fluid contains 1-ring and/or 2-ring aromatics and has a final boiling point ≦430° C. The invention also relates to the upgraded pyrolysis tar, and to the use of the upgraded pyrolysis tar, e.g., for fuel oil blending.
Abstract:
The present invention generally relates to a process for purifying vacuum tower asphalt extender (VTAE), from re-refined lubricants, or generally recycled oil via solvent treatment to afford a purified material from certain components with improved benefits for use for instance with petroleum products.
Abstract:
A method for producing high density fuels from isoprene which can be produced via biosynthetic routes using biomass sugars as feedstock. This allows for the production of isoprene and isoprene-derived fuels from abundant waste materials with the potential to significantly reduce DoD carbon emissions. Embodiments of the invention describe a method for conversion of isoprene to full performance jet and diesel fuels. Isoprene can be selectively oligomerized to generate a distribution of branched chain hydrocarbons. Combination of an oligomerization catalyst with a metathesis catalyst allows for the synthesis of high density cyclic fuels with performance advantages (increased density and volumetric net heat of combustion) over conventional petroleum-based fuels.
Abstract:
A bottom fraction of a product of a hydrocatalytic reaction is gasified to generate hydrogen for use in further hydrocatalytic reactions. In one embodiment, an overhead fraction of the hydrocatalytic reaction is further processed to generate higher molecular weight compounds. In another embodiment, a product of the further processing is separated into a bottom fraction and an overhead fraction, where the bottom fraction is also gasified to generate hydrogen for use in further hydrocatalytic reactions.
Abstract:
Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor seventies and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.
Abstract:
A system and method for processing biomass into hydrocarbon fuels that includes processing a biomass in a hydropyrolysis reactor resulting in hydrocarbon fuels and a process vapor stream and cooling the process vapor stream to a condensation temperature resulting in an aqueous stream. The aqueous stream is sent to a catalytic reactor where it is oxidized to obtain a product stream containing ammonia and ammonium sulfate. A resulting cooled product vapor stream includes non-condensable process vapors comprising H2, CH4, CO, CO2, ammonia and hydrogen sulfide.
Abstract:
A plant processing system of the present invention includes: a plant cultivation facility (1) which cultivates plants including a sugar solution; a crushing facility (2) which crushes plants felled in the plant cultivation facility (1); a juicing facility (3) which harvests sap from plant chips obtained by the crushing facility (2); a methane fermentation facility (5) which performs a methane fermentation process on the sap; and a power generation facility (6) which generates electric power using a biogas obtained by the methane fermentation facility (5) as a fuel.
Abstract:
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce an intermediate or product, e.g., by fermentation.
Abstract:
The present invention provides a blended fuel and methods for producing the blended fuel, wherein a low carbon fuel derived from a renewable resource such as biomass, is blended with a traditional, petroleum derived fuel. A blended fuel which includes greater than 10% by volume of low carbon fuel has an overall improved lifecycle greenhouse gas content of about 5% or more compared to the petroleum derived fuel. Also, blending of the low carbon fuel to the traditional, petroleum fuel improves various engine performance characteristics of the traditional fuel.
Abstract:
A jet-range hydrocarbon product includes a mixture of paraffins. The mixture exhibits a freeze point of less than or equal to about −70° C., a 95% distillation point of greater than or equal to about 275° C., and a smooth boiling point curve that is characterized as having no intervals of the boiling point curve having a slope that is steeper than 4° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%. The steepness of the boiling point curve slope is calculated over any 10 mass % increments within the specified mass % ranges.
