  • Patent number: 10392250
    Abstract: A reactor system for partial oxidation gasification includes a reactor vessel that has a defined reaction zone with a reaction zone inlet and a reaction zone outlet. An injector section is operable to inject reactants to the reaction zone inlet. A coolant injector is operable to inject a coolant adjacent a reaction zone outlet. A reactor vessel outlet is located downstream of the coolant injector. A controller is configured to operate the coolant injector with respect to cooling a synthesis gas discharged from the reaction zone outlet and upwardly shifting a ratio H2:CO to a target ratio.
    Type: Grant

  • Patent number: 9926501
    Abstract: An entrained-flow gasifier reactor includes a vessel and a first liner within the vessel. The first liner extends around a reaction zone in the vessel and has an inlet end and an exit end with respect to the reaction zone. The first liner includes a drip lip at the exit end. An isolator is arranged near the drip lip. The isolator is operable to thermally isolate the drip lip from a quench zone downstream from the reaction zone such that molten slag at the drip lip remains molten.

  • Patent number: 7740671
    Abstract: A dump-cooled gasifier includes a vessel, a liner, and coolant. The liner has a head end, an aft end, and a plurality of channels extending along a length of the vessel. The aft end of the liner is axially and radially expandable with respect to the head end of the liner. The coolant enters at the head end of the liner, flows through the liner, and is expelled from the aft end of the liner directly into the vessel.
