Patent ID: 6846848

Claim:
A process for forming a hydrocarbon wax product comprising (a) reacting a synthesis gas comprising a mixture of H 2 and CO in the presence of a solid, particulate hydrocarbon synthesis catalyst in a hydrocarbon synthesis shiny comprising said catalyst and a hydrocarbon liquid in a hydrocarbon synthesis zone of a reactor under reaction conditions effective to form a liquid hydrocarbon wax, said hydrocarbon liquid comprising said liquid hydrocarbon wax; (b) introducing a portion of said hydrocarbon synthesis shiny containing the liquid hydrocarbon wax into a treatment zone; (c) contacting said portion of said hydrocarbon synthesis shiny in said treatment zone with a hydrogen-containing treatment gas to form a treated slurry, said treated shiny comprising said catalyst particles and a treated hydrocarbon liquid, comprising a purified hydrocarbon wax; and, (d) separating the hydrocarbon wax from said treated slurry.
