| 摘要 | 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. | ||||||
