Abstract

The invention discloses a hydrogenation process for producing API III < + > lubricating oil base oil from Fischer-Tropsch synthetic oil. The Fischer-Tropsch synthetic oil is used as a raw material, and a hydrofining-hydro-upgrading-isodewaxing two-stage hydrogenation process is adopted to produce API III + lubricating oil base oil. The generated oil obtained by separation of hydrofining-hydro-upgrading reaction effluent enters an isodewaxing reaction zone; and the process further includes separating and fractionating the isodewaxing reaction effluent to obtain different types of API III + lubricating oil base oil products, cooling fractionated vacuum bottom oil to obtain an incompletely converted wax component, and returning the incompletely converted wax component to the hydro-upgrading reactor to continue the upgrading reaction. The invention 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 synthesis oil fraction hydrogenation.

Description

Technical field [0001] The invention relates to a Fischer-Tropsch synthetic oil production API Ⅲ + Hydrogenation process of base oil, specifically, a combined hydrogenation process to produce API Ⅲ + The method of lubricating base oil. Background technique [0002] In the Fischer-Tropsch process, syngas (CO+H 2 ) Catalytically converted into products that are basically linear hydrocarbons and oxygen-containing compounds, which can be in gaseous, liquid or solid form. These Fischer-Tropsch synthesis products contain extremely low sulfur, nitrogen, aromatics and cyclic compounds. The Fischer-Tropsch synthetic oil obtained by the 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, with very low sulfur and nitrogen content, and contains a certain amount of oxygen. [0003] Since the in...
