摘要:
The present invention relates to a method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) mobilizing said hydrocarbon mixture; (ii) recovering said mobilized hydrocarbon mixture; (iii) deasphalting said recovered hydrocarbon mixture to produce deasphalted hydrocarbon and asphaltenes; (iv) gasifying said asphaltenes in a gasifier to generate hydrogen, steam and/or energy and CO2; (v) upgrading said deasphalted hydrocarbon by hydrogen addition to produce upgraded hydrocarbon; and (vi) adding a diluent to said upgraded hydrocarbon, wherein said method is at least partially self-sufficient in terms of hydrogen and diluent.

In accordance with one embodiment, a process is described for a water treatment process in which water produced from a fuel production process is treated with recycled biochar. In accordance with one aspect, process water is passed through activated carbon generated by the biomass pyrolysis and gasification. In accordance with another aspect, the process water is treated to expel gaseous compounds within the process water. In this manner both inorganics, light organics and heavy organics can be removed from the process water. No fermentation is involved.

Reactors for carrying out a chemical reaction, as well as related components, systems and methods are provided. In accordance with one embodiment, a reactor is provided that includes a furnace and a crucible positioned for heating by the furnace. A downtube is disposed at least partially within the interior crucible along an axis. At least one structure is coupled with the downtube and extends substantially across the cross-sectional area of the interior volume taken in a direction substantially perpendicular to the axis. A plurality of holes is formed in the structure enabling fluid flow therethrough. The structure coupled with the downtube may include a lower body portion and an upper body portion coupled with the lower body portion, wherein the plurality of holes is formed in the lower body portion adjacent to, and radially outward from, a periphery of the upper body portion.

The disclosed embodiments relate to systems and methods for heating a slurry to increase a solids concentration of the slurry while maintaining the viscosity of the slurry below a threshold viscosity. For example, in one embodiment, a system includes a fuel slurry preparation system having a slurry tank configured to hold a fuel slurry, the fuel slurry having a solid fuel and a liquid. The fuel slurry preparation system also includes a heat source and a controller configured to control the heat source to heat the fuel slurry to decrease a viscosity of the slurry below a threshold viscosity.

摘要:
A solids feeder for transporting particulated solids from a solids feed supply into the bottom of a solids upflow vessel. The feeder includes a pair of solids feed chutes, each terminating in a bottom outlet located in essentially the same horizontal plane as the bottom solids inlet of the solids upflow vessel and on opposite sides of the bottom solids inlet. A pair of solids feed cylinders provided with hydraulically actuated pistons are vertically mounted in spaced relationship on a reciprocating carriage positioned below the solids upflow vessel. The carriage is reciprocated between two stationary positions in which the cylinders alternately fill with particulated solids and discharge the solids into the bottom of the solids upflow vessel.

A method includes providing a gasifier with a fuel source comprising a heavy oil, a light oil, and recovered soot. The gasifier may gasify the fuel source to generate a syngas and soot. The method also includes recovering the soot in a first separation unit that may receive a portion of the heavy oil and separate the soot from an extraction oil used to recover the soot. The first separation unit generates soot bottoms that include the portion of the heavy oil and the recovered soot. The method also includes flowing a first separation co-fractionate to a second separation unit. The first separation co-fractionate includes the extraction oil and the light oil. The second separation unit may separate the extraction oil and the light oil, and direct the light oil towards the first separation unit. The method further includes mixing the soot bottoms from the first separation unit with the light oil from the second separation unit to generate the fuel source and directing the fuel source to the gasifier for gasification.
