Abstract: Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

Abstract: The present disclosure relates to producing hydrocarbons from a feedstock containing organic material of biological origin. An exemplary process includes providing a feedstock including organic material of biological origin; pre-treating the feedstock in one or more pre-treatment stages to obtain a purified feedstock; subjecting the purified feedstock to pre-hydrotreatment to obtain a stream of partly hydrotreated feed; subjecting the stream of partly hydrotreated feed to hydrotreatment to obtain a stream of hydrocarbons; subjecting the stream of hydrocarbons to isomerisation to obtain an isomerised stream of hydrocarbons; and distilling the isomerised stream of hydrocarbons to obtain at least two fractions, a first heavy bottom fraction and a second middle fraction, at least one of which is collected as a product of hydrocarbons.

Abstract: A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

Abstract: Systems and methods are provided for integration of electrolysis with biomass gasification to generate synthesis gas that can be used for production of renewable fuels and/or other hydrocarbonaceous compounds. The hydrocarbonaceous compounds can include compounds formed by chemical synthesis, such as alkanes formed by a Fischer-Tropsch process or methanol formed by a methanol synthesis process; or the hydrocarbonaceous compounds can include compounds formed by fermentation, such as alcohols formed by micro-organisms that use the synthesis gas as an input feed.

Abstract: A distillate boiling range composition is provided with an unexpected distribution of carbon chain lengths for the hydrocarbons in the composition. The composition corresponds to a distillate boiling range composition with a relatively narrow boiling range. Additionally, the narrow boiling range composition can have unexpectedly beneficial cold flow properties.

Abstract: A geothermal system including a heat-driven process system using heat extracted from a magma wellbore for driving a thermal process. The system includes a magma wellbore connected to the heat-driven process system in a closed loop. A heated heat transfer fluid conveys the heat from the magma wellbore to a reactor housing a decomposition reaction. The reactor can be a batch reactor, a continuous reactor, or a through-flow reactor. The heat provides the reaction temperature necessary for driving the decomposition reaction of a polymer to an end product. The heat can be provided directly by the heated heat transfer fluid, by an intermediate heat transfer fluid heated by the heated heat transfer fluid, or by a reaction medium heated by the heated heat transfer fluid.

Abstract: According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.
