    摘要: Catalyst in a slurry phase reactor is rejuvenated and uniformly distributed in said reactor using a substantially vertical draft tube fully immersed in the slurry which utilizes a rejuvenating gas injected substantially near the bottom of the substantially vertical draft tube whereby catalyst near the bottom of the slurry phase reactor is drawn up the draft tube and discharged from the top of the draft tube near the top of the slurry phase in said reactor.

    摘要: The operation of a hydrocarbon synthesis reactor and catalyst distributed in the reaction slurry therein are improved by the presence in said reactor of one or more vertical downcomers open at both ends with gas disengaging areas located at their top end. The downcomer which circulates catalyst from the top of the reaction slurry to the bottom of said slurry is fully immersed in the reaction slurry and preferably extends from just above the bottom of the reaction zone of the reaction vessel to just below the top surface of the reaction slurry. The bottom end of said downcomer is shielded from intrusion of rising synthesis gas by the placement of a baffle which blocks rising gas entry but facilitates the exit of catalyst and liquid from the bottom of said downcomer and distributes them radially throughout the adjacent reactor slurry.

    摘要: A slurry hydrocarbon synthesis process with reduced catalyst attrition is achieved by injecting a synthesis gas comprising a mixture of H.sub.2 and CO up into the reactive slurry with a gas distribution grid having gas injectors horizontally arrayed across, and vertically extending through, an otherwise gas and liquid impervious plate. The injectors have a throat with a gas pressure reducing orifice at one end, which is the bottom and gas entrance end, and the other end opening into an open cone in which the uprising gas contacts the slurry. Flow diverting means in the injectors prevents slurry from entering the throat and being attrited. The gas injectors do not protrude above the top surface of the plate and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the tray.
