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 CO.sub.2; (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 process water 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.

A process for the production of a liquid fuel from carbon oxides and hydrogen is disclosed. The process comprises reacting a mixture of carbon oxides and hydrogen to produce methanol. The methanol is contacted with an MTO catalyst to produce an olefin stream. The olefin stream is oligomerized with an oligomerization catalyst to produce an oligomerized olefin stream which is then hydrogenated to produce the liquid fuel streams jet fuel, diesel, and naphtha. At each stage, waste streams are produced. A syngas stream is produced comprising carbon oxides and hydrogen by (1) steam reforming, autothermal reforming, or dry reforming; or (2) partial oxidization.

Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510 C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510 C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks. The catalytic processing can correspond to processing in at least two stages. The amount of conversion performed in each stage can be varied to produce bright stocks with various properties.

Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.

Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

Various embodiments disclosed relate to cooling shale gas via reaction of methane, light hydrocarbons, or a combination thereof, with water. In various embodiments, the present invention provides a method of cooling syngas. The method includes contacting the hot syngas with methane or light hydrocarbons. The hot syngas includes water and has a temperature of about 800 C. to about 3000 C. The contacting is effective to endothermically react the methane or light hydrocarbons with the water in the hot syngas to form carbon monoxide and hydrogen and to provide a cooled syngas having a lower temperature than the hot syngas.

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.
