Abstract

The invention discloses a processing method of Fischer-Tropsch synthetic oil. Using Fischer-Tropsch synthetic oil as raw material, the two-stage hydrogenation process of hydrorefining-hydro-upgrading-isomerization dewaxing is used 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 + Lubricant base oil products. 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 invention relates to a Fischer-Tropsch synthetic oil production API III + Hydrogenation method of base oil, specifically a method for producing API III by hydrogenation combined process + Hydrogenation of lubricating base oils. Background technique [0002] In the Fischer-Tropsch process, syngas (CO+H 2 ) are catalytically converted into products that are 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 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 paraffin and It is composed of olefins, and has a very low sulfur and nitrogen content, and contains a certain amount of o...
