HEAVY LUBE OIL FROM FISCHER-TROPSCH WAX

摘要

A heavy lubricant base stock is made by (a) producing a synthesis gas from natural gas, (b) reacting the H2 and CO in the gas in the presence of a coba lt Fischer-Tropsch catalyst, at reaction conditions effective to synthesize wax y hydrocarbons boiling in the heavy lubricant oil range, which are hydrodewaxe d it at least two stages, with interstage separation and removal of the lighte r material.
