Abstract: Methods and apparatus for separating liquid products and catalyst fines from a slurry used in a Fischer-Tropsch reactor. A settling system continuously or intermittently removes catalyst fines from the slurry and is coupled with catalyst-liquid separation system that separates liquid products from the slurry. The preferred separation system produces a sub-particle rich stream and a catalyst-lean stream that are removed from the system. The systems of the present invention act to reduce the concentration of catalyst fines in the reactor, thereby increasing the effectiveness of a catalyst-liquid separation system.
