Methods, processes, apparatus, systems, and compositions are disclosed for improving the sustainability of oil sands processing. In some embodiments, bitumen is combined with biodiluent comprising one or more liquid pyrolysis fractions obtained from pyrolyzing biomass and collecting multiple liquid fractions. The bitumen may be any source of bitumen, such as bitumen obtained from oil sands. In some embodiments, a water-rich pyrolysis liquid displaces water use in an oil sands process. The water-rich pyrolysis liquid may be used for primary separation of bitumen from oil sands or for hydrotransport, for example. Also, biochar produced from biomass pyrolysis may be introduced to an oil sands tailing pond with various benefits. Water may be recycled from a tailing pond. Integration of a pyrolysis and separation process into an oil sands refining process reduces the overall greenhouse-gas emissions on a well-to-refined product basis by 10-70% or more. Various compositions and products are also disclosed.

摘要:
A process for production of oil-rich microalgae is disclosed, which includes methods for cultivating strains of Characium polymorphum and/or Ankistrodesmus braunii (Chlorophyceae), or isolated variants thereof, in order to produce oil at optimum levels. The process is suitable for large-scale productions. The invention also discloses methods for purifying the microalgae cells, and methods for treating the microalgae cells to enrich their oil content. In addition, various representative culturing media as well as conditions for cultivating microalgae and inducing oil accumulation are also disclosed. The oil-rich microalgae produced by the process can be used as feedstock for biofuel production.
摘要:
The present invention provides compositions, methods, apparatus, and systems to minimize environmental impact, water use, and overall cost of drilling and hydraulic fracturing for crude oil and natural gas. Some variations of the invention provide a fracturing-fluid additive composition comprising a water-soluble portion of a biomass-pyrolysis liquid. In some embodiments, the fracturing-fluid additive composition is substantially biodegradable and is not toxic. Some variations provide improved proppants for oil or gas well fracturing. Other variations of this invention relate to drilling-fluid additive compositions, and methods of using these compositions. This invention can significantly improve the environmental, economic, and social sustainability associated with drilling and fracturing for production of oil and gas.
摘要:
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.
