Abstract

The invention discloses a processing method of Fischer-Tropsch synthetic oil. Fischer-Tropsch synthetic oil is used as a raw material, and a two-stage hydrogenation process of hydrofining-hydro-upgrading-isodewaxing is adopted to produce API III <+> lubricating oil base oil. Generated oil obtained through separation of a hydrofining-hydro-upgrading reaction effluent enters an isodewaxing reactionzone, and different types of API III <+> lubricating oil base oil products are obtained through separation and fractionation of an isodewaxing reaction effluent. The method has the advantages of simple process flow and wide raw material adaptability, and can be suitable for the process of producing special oil products with good stability by Fischer-Tropsch synthetic oil fraction hydrogenation.

Description

technical field [0001] The invention relates to a Fischer-Tropsch synthetic oil production API III + Hydrogenation method of base oil, specifically a hydrogenation combined process to produce API III + Hydrogenation method of lubricating base oil. Background technique [0002] In the Fischer-Tropsch process, the syngas (CO+H 2 ) to products of catalytic conversion to essentially straight-chain hydrocarbons and oxygenates, which may be in gaseous, liquid or solid form. These Fischer-Tropsch synthesis products are extremely low in sulfur, nitrogen, aromatics and cyclic compounds. The Fischer-Tropsch synthetic oil obtained by Fischer-Tropsch synthesis technology is quite different from conventional petroleum derivatives in terms of hydrocarbon composition and main properties. It is a substance with high wax content, mainly composed of paraffins and It is composed of olefins, and the content of sulfur and nitrogen is extremely low, and it contains a certain amount of oxygen....
