Abstract: In a catalytic process for converting synthesis gas including hydrogen and carbon monoxide to hydrocarbons and oxygenates by a slurry Fischer-Tropsch synthesis, the wax product along with dispersed catalyst is removed from the slurry and purified by removing substantially all of the catalyst prior to upgrading the wax and returning a portion to the Fischer-Tropsch reaction. Separation of the catalyst particles from the wax product is accomplished by dense gas and/or liquid extraction in which the organic compounds in the wax are dissolved and carried away from the insoluble inorganic catalyst particles that are primarily inorganic in nature. The purified catalyst free wax product can be subsequently upgraded by various methods such as hydrogenation, isomerization, hydrocracking, conversion to gasoline and other products over ZSM-5 aluminosilicate zeolite, etc.

Abstract: A punching tool having a solid barrel adapted for hand holding, and having at one barrel end a head for hammering, and at the other barrel end a tapered neck. A threaded nut is removably attached to the barrel intermediate the neck and second barrel end. A plurality of attachment tips are provided, each having an internal tapered bore sized to fit over the tapered neck of the second barrel end, and each is removable by rotation of the threaded nut on the barrel.
