  • Patent number: 10899983
    Abstract: Marine diesel fuel/fuel blending component compositions and fuel oil/fuel blending component compositions are provided that are derived from crude oils having high naphthenes to aromatics volume and/or weight ratios and a low sulfur content. In addition to having a high naphthenes to aromatics ratio, a low sulfur content, and a low but substantial content of aromatics, such fuels and/or fuel blending components can have a reduced or minimized carbon intensity relative to fuels derived from conventional sources. The unexpected ratio of naphthenes to aromatics contributes to the fuels and/or fuel blending components further having additional unexpected properties, including low density, low kinematic viscosity, and/or high energy density.

  • Patent number: 9738909
    Abstract: A method is provided to transform biomass. Non-food biomass is preprocessed. Then, fermentation is processed to generate ethanol. Ethanol is dehydrated through a catalyst to generate ethylene. After the dehydration, oligomerization is processed with a catalyst to transform ethylene into olefins having 6˜20 carbon atoms (C6˜C20). The olefins are hydrotreated into alkanes. Thus, C6˜C20 hydrocarbons having long carbon chains are formed. The hydrocarbons having 6˜10 carbon atoms can be used as gasoline; those having 8˜16 carbon atoms, jet fuel; and those having 16˜20 carbon atoms, diesel. On generating ethanol, byproducts of lignin may be generated. The byproducts can be processed through depolymerization/deoxygenation to generate aromatic hydrocarbons or can be gasified to generate methanol or dimethyl ether. By further processing dehydration, aromatic hydrocarbons are generated to be mixed into gasoline, jet fuel or diesel. Or, the lignin byproducts are gasified to generate syngas.

  • Patent number: 9057033
    Abstract: Provided are a method and a device for producing synthesis gas and for operating an internal combustion engine therewith. The engine fuel gases can be produced from changing heterogeneous organic fuels, wherein highly tar-laden product gas and pyrolysis gas are formed. The gas mixtures or the syntheses gas formed and by special operation of the gas engine are usable as an addition to the ignition oil. The synthesis gas is generated from the pyrolysis gas that is generated in a pyrolysis reactor and from the product gas that results from autothermal gasification of the pyrolysis coke formed and/or of the pyrolysis oil in an atmospheric steady-state fluidized bed gasifier. Then purifying the synthesis gas in a gas scrubber and in an tar electrostatic filter, passing the synthesis gas via a compressor into a separate injector of a two-stroke dual-fuel engine, bypassing turbocharger and intercooler.

  • Patent number: 9028675
    Abstract: This invention relates to a method for increasing thermal stability of fuel, as well as in reducing nitrogen content and/or enhancing color quality of the fuel. According to the method, a fuel feedstock can be treated with a solid phosphoric acid catalyst under appropriate catalyst conditions, e.g., to increase the thermal stability of the fuel feedstock. Preferably, the fuel feedstock can be treated with the solid phosphoric acid catalyst at a ratio of catalyst mass within a contact zone to a mass flow rate of feedstock through the zone of at least about 18 minutes to increase the thermal stability of the fuel feedstock, along with reducing nitrogen content and/or enhancing color quality.

    Abstract: Fuel compositions containing an isomerized component of a single carbon number may contain at least 97 wt. %, based on the total weight of the fuel composition, of an isomerized component consisting of aliphatic paraffin isomers all having the formula CnH2n+2, where 10?n?22 and n has the same value for each aliphatic paraffin isomer in the isomerized component. The fuel compositions have a normal alkane content of less than 10 wt. %, based on the total weight of the fuel composition. Methods for preparing the fuel compositions include hydroisomerizing a normal alkane starting material to form an isomerized mixture and subsequently removing remnant normal alkanes from the isomerized mixture by solvent dewaxing and/or distillation. Some of the fuel compositions may have freezing points at or below ?47° C., making them amenable for use a surrogate fuels in the place of JP-8.
