  • Patent number: 10072225
    Abstract: The present invention relates to a process and apparatus for conversion of organic material into hydrocarbon based fuel such as an oil and relates in particular to a process and apparatus for recovering alkali salts and/or water soluble organics from water effluents from hydrothermal conversion processes of organics such as biomass and/or organic waste and/or other organic materials such as bitumen or lignite coal into oil in hot pressurized water. Another aspect of the invention relates to an integrated process for effective production of oil by conversion of slurries of biomass and/or organic waste and/or other organic materials such as bitumen or coal in hot pressurized water, wherein alkali salts and/or water soluble organics are recovered from the water effluent and is at least partly recycled to the feeding step thereby resulting in both a cleaned water effluent from the process as well as a more effective and economic process.
