  • Method of operating a slurry bubble column reactor
    Patent number: 11505749
    Abstract: A method for starting a slurry bubble column reactor that includes a reactor vessel holding a settled or slumped bed of particles and a liquid phase from which the particles have settled includes introducing a flow of a re-suspension liquid into the settled or slumped bed to loosen the settled or slumped bed. The introduction of the re-suspension liquid takes place before the introduction of any gas into the settled or slumped bed, or together with feeding of gas into the settled or slumped bed, provided that, if gas is fed together with the re-suspension liquid into the settled or slumped bed before the settled or slumped bed has been loosened, the gas has a superficial gas velocity in the reactor below 10 cm/s. Once the settled or slumped bed has been loosened by at least the re-suspension liquid, gas is passed at a superficial gas velocity above 10 cm/s through the liquid phase.
