Embodiment 1

[0042] Such as figure 1 As shown in the process, the existing commercial catalyst is selected, the hydrotreating reaction zone uses the hydrofinishing catalyst FF-26, the hydrogenation upgrading reaction zone uses the hydrogenation upgrading catalyst FC-14, and the isomerization dewaxing reaction zone uses the iso Constructed dewaxing catalyst FIW-12. In the oil produced by hydrofining, the cut point of the light fraction and the heavy fraction is 280 °C. The cutting point of hydrogenated light components and heavy components is 320 ℃. See 2-3 for process conditions and results.

Embodiment 2

[0044] process such as figure 1 shown. Adjust the upgrading conversion rate, see 2-3 for the process conditions and results.

Embodiment 3

[0046] process such as figure 1 shown. Adjust the upgrading conversion rate, see 2-3 for the process conditions and results.

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. Heavy distillate oil generated oil obtained through hydrofining-hydro-upgrading reaction effluent separation enters an isodewaxing reaction zone, and an isodewaxing reaction effluent is subjected to separation and fractionation to obtain different types of API III <+> lubricating oil base oil products. 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 fractionhydrogenation.

Description

technical field [0001] The invention relates to a processing method of Fischer-Tropsch synthetic oil, in particular to a method for producing API III by hydrogenation combined process + 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 oxygen. [0003] Due to the introduction o...
