  • Reactor and method for upgrading heavy hydrocarbons with supercritical fluids
    Patent number: 10920152
    Abstract: Heavy hydro-carbonaceous materials such as bitumen are upgraded in supercritical water in a continuous-flow reactor system. The present invention provides a reactor arrangement for and a method of converting bitumen and other highly viscous hydrocarbon containing materials into pumpable liquids to enable further processing of such materials while avoiding production of char. The process can be carried out in an underground reactor based on oil well technology. The reactor design and method facilitates mass transfer to dissolve bitumen in heated water and breaks down heavy hydrocarbons by controlling the temperature and pressure in zones within the flowing stream. The reactor may include an embedded electric heater.
