摘要： A process and apparatus for the continuous conversion of isotropic carbonaceous materials into anisotropic mesophase pitch is disclosed. The invention disclosed herein addresses the need for lower production costs compared with traditional batch mesophase conversion of isotropic pitch. A unique thermal processing and in-process separation of reacted mesophase from the continuous matrix of fresh or partially reacted isotropic pitch is provided. Potential uses are for further continuous processing into carbon fibers or carbon form densification.

摘要： A system for producing biomass vinegar and charcoal includes a furnace, which has an outer shell defining a lower combustion chamber and an upper heating chamber, and an inner tank removably received in the heating chamber. A cooling pond has a cooling region to accommodate the inner tank. A condenser in a collection barrel condenses smoke gases from the inner tank to produce biomass vinegar. A first temperature sensing pipeline removably connects the inner tank, After the biomass is carbonized, the first temperature sensing pipeline is removed from the inner tank, and the inner tank is moved to the cooling region to be cooled by a sprinkler.

摘要： Methods of processing a coal-based feedstock to a high value product are provided. In one embodiment a method of processing a coal-based feedstock to a high value product, the method comprises the steps of: contacting the coal-based feedstock with one or more solvents under non-pyrolytic conditions thereby generating a liquid phase; and fractionating the liquid phase to generate at least two fractions under conditions such that at least one of the fractions is the high value product. The liquid phase may comprise 5 to 25 wt % oxygen and at least 70% of the oxygen in the liquid phase may be in the form of phenolic, carboxylic and ketone functional groups of hydrocarbon-based compounds.

摘要： Disclosed herein are methods of preparing bitumen for transport, apparatus for preparing bitumen for transport, methods of transporting bitumen, and transportation-ready forms of bitumen. Instead of relying on exogenous components to induce bitumen solidification, the methods and apparatus of the present disclosure reorganize bituminous materials derived from the same origin into core-shell bitumen microcapsules, such that relatively low solubility components (e.g. asphaltenes) encapsulate relatively high solubility components (e.g. maltenes). Importantly, the bitumen microcapsules of the present disclosure are sufficiently mechanically resilient to meet one or more thresholds for midstream transportation, and they are readily fluidized for downstream processing with conventional technologies. Taken together, these aspects may ameliorate one or more challenges in achieving commercially viable bitumen solidification technologies.

摘要： A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.

摘要： Apparatus and method for recycling asphalt millings containing bitumen and stone. A milling tube is provided having an outer tube and an inner tube axially aligned with and substantially contained within the outer tube, the inner tube having a diameter less that a diameter of the outer tube to thus define a mixing space between the inner and outer tubes. At least one of the inner and outer tubes is adapted to rotate relative to the other. An inlet is provided to the mixing space to receive the asphalt millings. A plurality of inner tube projections project radially outward from a surface of the inner tube toward the outer tube, and a plurality of outer tube projections project radially inward from a surface of the outer tube toward the inner tube. The milling tube facilitates the separation of the asphalt millings into bitumen and stone as one of the inner and outer tubes rotates relative to the other. Preferably, at least one of the outer and inner tubes contains an abrasive coating on a surface thereof, the inner tube projections and outer tube projections are comprised of wire rope, and an inlet is provided in the outer tube through which cold air can be applied to the mixing space.

摘要： 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.
