ABSTRACT:
A hydrocarbon wax product from a hydrocarbon synthesis slurry comprising liquid synthesis product and catalyst particles is purified by introducing a portion of hydrocarbon synthesis slurry from a hydrocarbon synthesis zone to a treatment zone in which a treatment gas contacts the hydrocarbon synthesis slurry. Hydrogen or a hydrogen-containing gas is useful as the treatment gas. The gas treatment removes impurities from the hydrocarbon wax portion of the hydrocarbon synthesis slurry. Purified wax product is separated and removed in situ via wax withdrawal means. This avoids or minimizes the need for further treating the wax product.
