Abstract

The invention discloses a method for producing API III from Fischer-Tropsch synthetic oil + Hydrogenation process of lube base oil. Using Fischer-Tropsch synthetic oil as raw material, adopt the two-stage hydrogenation process of hydrofining-hydro-upgrading-isomerization dewaxing to produce API III + Lubricant base oil. Hydrofining - The resulting oil obtained from the separation of the hydrogenation upgrading reaction effluent enters the isomerization dewaxing reaction zone, and the isomerization dewaxing reaction effluent is separated and fractionated to obtain different types of API III + The lubricating oil base oil product, the incompletely converted wax component obtained by cooling the fractionated reduced bottom oil is returned to the hydrogenation reforming reactor to continue the reforming reaction. The invention has simple technological process and wide adaptability of raw materials, and can be applied to the process of producing special oil products with good stability through hydrogenation of Fischer-Tropsch synthetic oil distillate.

Description

technical field [0001] The present invention relates to a kind of Fischer-Tropsch synthetic oil production API III + The hydrogenation process of base oil, specifically a hydrogenation combined process to produce API III + Lubricant base oil method. 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 oxyge...
