Abstract:
The invention relates to a method for producing a biofuel from an aqueous mixture of carbonised biomass obtained by means of a method for the hydrothermal carbonisation of biomass, characterised in that it comprises: (a) grinding the aqueous mixture of carbonised biomass until a maximum size of less than 500 micrometres of the particles contained in the mixture is obtained; (b) applying a method for the physical separation of inorganic substances; and (c) reducing the moisture content until a water content of between 25 and 55 wt. % is reached. The invention also relates to the biofuel obtained by said method, and to the use thereof in various applications.
Abstract:
Mixed alcohol formulas can be used as a fuel additive in petroleum-based hydrocarbon liquid fuels, synthetic or bio-derived gasoline, diesel fuels, jet fuel, aviation gasoline, heating oil, bunker oil, coal, petroleum coke, heavy crude oil, bitumen, or as a neat fuel in and of itself. The mixed alcohol formulations can be blended with ground petroleum coke, coal, heavy crude oil, or bitumen to form a thixotropic slurry for ease of transportation. The mixed alcohol formulations can also be used to shurry transport ground biomass. The mixed alcohol formulations can contain a blend of C1-C5 alcohols, or C1-C8 alcohols or higher C1-C10 alcohols in order to further boost energy content.
Abstract:
The invention provides a liquefaction process using comminuted fuel solids from a steam-driven shear field, with controlled water content and optionally coated with a catalyst. The method allows fuel solids to be liquefied efficiently during comminution or when they are supplied in the form of a slurry or as free-standing solids.
Abstract:
A coal processing method includes adding coal powder, water and catalyst into a series of tandem reactors and processing therein, wherein the coal powder, water and catalyst are added into the first reactor of the series of tandem reactors; and the temperature and pressure of the series reactors is alternatively arranged in sub-critical state and supercritical state of water from the first reactor, the total product from the previous reactor is used as the feed of the next reactor without any further separation.
Abstract:
A fuel composition for use in internal-combustion engines has a fuel component, an alcohol component, a water component, a microemulsion blend, and a cetane-enhancer component. The microemulsion blend includes at least one of lower grade fatty acid derivatives being present in an amount effective for the fuel, alcohol, and water components to form a microemulsion blend. The emulsifier is present in an amount effective for the biodiesel fuel, alcohol, water, and emulsifier to form an emulsion.
Abstract:
Provided herein are, inter alia, heavy crude oil emulsion compositions and methods of making the same. The compositions and methods provided herein are particularly useful for the transport of heavy crude oils.
Abstract:
An emulsification method for converting deasphalted oil and/or asphaltenes into more suitable products for market demands and utilization in self sufficient energy production treatments plants is disclosed. Asphaltenes and residues from sonication of heavy oil feedstocks, as well as de-asphalted oil, may be used in combination with water and other chemical additives for conversion into a suitable fuel which may be stored, handled, and transported.
Abstract:
Liquid suspensions are disclosed comprising a suspending medium, small particles of biomass, and small particles of an inorganic material. The inorganic material stabilizes the suspension, so that it may be transported by pipeline or tank car without developing a sediment.The suspension may be used in manufacturing a bio-fuel.
Abstract:
Disclosed embodiments include a feedstock preparation system that includes a first slurry preparation system that may receive a first portion of a solid fuel to generate a first fuel slurry using the first portion of the solid fuel and a liquid and second slurry preparation system separate from the first slurry preparation system that may receive a second portion of the solid fuel and the first fuel slurry. The second slurry preparation system may produce a second fuel slurry using the second portion of the solid fuel and the first fuel slurry. The first fuel slurry has a first particle size distribution and the second fuel slurry has a second particle size distribution, and the first and second particle size distributions are different.
Abstract:
Method for making a slurry of a pulverized solid in liquid or supercritical carbon dioxide. The method includes making a water-pulverized solid slurry at ambient pressure and pressurizing the water-pulverized solid slurry to a high pressure. The pressurized water-pulverized solid slurry is mixed in a pressurized chamber with liquid or supercritical CO2 to form a CO2˜pulverized solid slurry.
