A kind of method for processing Fischer-Tropsch wax production series products

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 ...

AI Technical Summary

Problems solved by technology

The disadvantages are as follows: 1. The raw material does not undergo any pretreatment process, and is directly evaporated at high temperature. Due to the small amount of olefins, oxygen-containing organics and polycyclic hydrocarbons in the raw material, carbon deposition and coking are likely to occur during the separation process, which affects the product. Quality; 3. It is limited to the separation of raw materials, and there is no follow-up treatment process, and the purpose of the product is not strong
