Abstract
Methods, systems and units for liquefaction of combustible material are provided. After separating the combustible material from waste rock gravitationally in an aqueous salt solution selected to have a density which is intermediate between a density of the combustible material and a density of the waste rock and after heating and grinding the separated combustible material to yield a paste of purified combustible material, the paste is fluidizing and hydrogenated underground in a hydrogenation chamber including a Segner turbine. The described processes significantly reduce the energy consumption of the process, remove environmental hazards and result in more efficient liquefaction with respect to existing technologies.

A method of separating and hydrogenating combustible material, the method comprising:
- separating the combustible material from waste rock gravitationally in an aqueous salt solution selected to have a density which is intermediate between a density of the combustible material and a density of the waste rock;
- heating and grinding the separated combustible material to yield a paste of purified combustible material;
- fluidizing the paste;
- and
- hydrogenating the fluidized paste in association with a Segner turbine.
A system for processing combustible material, comprising:
- a floating subsystem arranged to gravitationally separate the combustible material from waste rock in an aqueous salt solution selected to have a density which is intermediate between a density of the combustible material and a density of the waste rock;
- a heated grinding subsystem arranged to heat and grind the separated combustible material to yield a paste of purified combustible material;
- a paste fluidizing subsystem arranged to fluidize the paste;
- and
- a hydrogenation subsystem arranged to hydrogenate the fluidized paste in association with a Segner turbine.
A hydrogenation unit comprising:
- a vertical shaft arranged to receive a fluid combustible material and maintain a downwards flow thereof;
- a Segner turbine in fluid communication with the vertical shaft and arranged to be rotated by the flowing fluid combustible material;
- a hydrogenation chamber enclosing a bottom portion of the vertical shaft and the Segner turbine, the hydrogenation chamber comprising a heating unit arranged to heat the fluid combustible material and a hydrogen supply arranged to introduce hydrogen into the fluid combustible material that exits the Segner turbine, to yield a hydrogenated combustible fluid;
- and
- a vertical enclosure in fluid communication with the hydrogenation chamber and arranged to maintain an upwards flow of the hydrogenated combustible fluid from the hydrogenation chamber while enabling recuperative heat exchange between the rising hydrogenated combustible fluid and the downwards flow of fluid combustible material.
