Abstract: The disclosure deals with a slurry bubble column reactor for converting a gas mixture comprising carbon monoxide and hydrogen into liquid hydrocarbons. The slurry bubble column reactor features a slurry bed of catalyst particles, an inlet conduit for feeding the gas mixture into the slurry bed, a filtration zone for separating the liquid hydrocarbons from the catalyst particles and a liquid outlet conduit for withdrawing the separated hydrocarbons from the filtration zone. The filtration zone is situated in the slurry bubble column reactor such that the slurry bed is found in a first and a second heat exchange zone with the filtration zone arranged between the first and the second heat exchange zone.

Abstract: The invention provides a method, stage and plant for removing LTFT catalyst fines and/or organometallic catalyst compounds from of LTFT wax, downstream from the LTFT reactor. The method includes at least one stage having the steps of causing a differential pressure across a filter element; causing high mechanical shearing and/or centrifugal forces along and/or away from the surface of the filter on the high pressure side of the filter to cause the particles to be continuously removed from the filter surface; and wherein the differential pressure is selected to be sufficient to force flow of the wax across the filter to cause filtration.
