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 Table 2-3 for process conditions and results.

Embodiment 2

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

Embodiment 3

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

Abstract

The invention discloses a processing method of Fischer-Tropsch synthetic 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 heavy distillate oil produced by 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 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...
