Embodiment 1

[0048] The Fischer-Tropsch synthetic filter wax obtained by a low-temperature Fischer-Tropsch synthesis process is used as raw material, and the hydrogenated filter wax is obtained through hydrogenation refining. The hydrogenation temperature is 310 ° C, and the reaction pressure is 6 MPa. The properties of the material before and after hydrogenation are shown in Table 1. The hydrogenation filtration wax enters the thin-film evaporator, the operating temperature is 250°C, and the operating pressure is 30Pa, and the hydrogenation filtration wax is separated into a Fischer-Tropsch light wax oil component and a Fischer-Tropsch heavy wax group with an end boiling point of about 500°C point. The Fischer-Tropsch light wax oil component enters the deoiling unit, and the deoiled Fischer-Tropsch light wax enters the short-path evaporator with an operating temperature of 125°C and an operating pressure of 0.7Pa to evaporate the diesel fraction and the remaining Fischer-Tropsch light wax ...

Embodiment 2

[0059] Fischer-Tropsch synthesis filter wax obtained by another Fischer-Tropsch synthesis process was used as raw material, and hydrogenated filter wax was obtained through hydrogenation refining. The hydrogenation temperature was 300°C and the reaction pressure was 10MPa. The hydrogenated filtration wax enters the thin-film evaporator, the operating temperature is 260°C, and the operating pressure is 30Pa, and the hydrogenated filtration wax is separated into a Fischer-Tropsch light wax oil component and a heavy Fischer-Tropsch wax component with an end boiling point of about 600°C . The Fischer-Tropsch light wax oil component enters the deoiling unit, and the deoiled Fischer-Tropsch light wax enters the short-path evaporator with an operating temperature of 125°C and an operating pressure of 0.7Pa to evaporate the diesel fraction and the remaining Fischer-Tropsch light wax The high quality wax component enters the next stage evaporator. The Fischer-Tropsch light wax compone...

Abstract

The invention provides a method for processing Fischer-Tropsch wax production series products. The method comprises: carrying out hydrofinishing on a Fischer-Tropsch wax raw material F to prepare a hydrofinished material FR; separating FR to obtain a light component material L and a heavy material H; carrying out oil removing operation on L to obtain an oil-removed light component material LDO; separating LDO to obtain a light component material LL1 and a remaining component material LH1; carrying out improvement of physicochemical properties on LL1 and forming so as to obtain a lightweight product LP1; treating LH1 according to the processes of the steps (4) and (5) to obtain a lightweight product LP2 and a remaining component material LH2; treating LH2 according to the processes of the steps (4), (5) and (6) to finally obtain a series of lightweight products LP3,..., LPN, and LPNN; separating H to obtain a light component material HL1 and a remaining component HH1; carrying out improvement of physicochemical properties on HL1 andforming so as to obtain a heavyweight product HP1; treating HH1 according to the processes of the steps (8) and (9) to obtain a heavyweight product HP2 and a remaining component material HH2; and treating HH2 according to the processes of the steps (8), (9) and (10) to finally obtain a series of heavyweight products HP3,..., HPN, and HPNN.

Description

technical field [0001] The invention relates to a method for processing Fischer-Tropsch wax production series products. Background technique [0002] Wax is a widely used chemical raw material, which plays many unique roles in different chemical fields. Its essence is a mixture of various high-carbon hydrocarbons, which exist in a solid state at room temperature. The approximate sources of wax are: pure natural wax, modified natural wax, semi-synthetic wax and synthetic wax. At present, the largest source of wax products is obtained from the separation and processing of petroleum, and the main products are petroleum wax and microcrystalline wax. Synthetic wax generally refers to polyethylene wax and Fischer-Tropsch synthetic wax. [0003] Petroleum wax and microcrystalline wax are mainly composed of normal alkanes or isoparaffins below C50, polyethylene wax is mainly composed of hydrocarbons above C60, and the carbon number distribution of Fischer-Tropsch wax is from C12 ...
