    摘要： A process for producing liquid and, optionally, gaseous products from gaseous reactants comprises feeding gaseous reactants into a slurry bed of solid particles suspended in a liquid; allowing the reactants to react as they pass upwardly through the slurry bed, thereby to form liquid and, optionally, gaseous products; and separating liquid product from the solid particles by passing, in a filtration zone within the slurry bed, liquid product through a filtration medium in a first direction, so that a cake of the solid particles forms on the filtration medium. The passage of liquid product through the filtering medium is interrupted. The filtering medium is then backflushed by passing a flushing fluid through the filtering medium in a second direction, opposite to the first direction, for at least portions of the periods that the liquid product passage is interrupted, thereby to dislodge the cake from the filtering medium.

    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.
