Problems solved by technology

[0004] At present, most of the Fischer-Tropsch synthetic heavy wax processing schemes are for the purpose of catalytic cracking or hydrocracking to produce fuel oil. As mentioned above, the economic efficiency is poor
In addition, high-boiling Fischer-Tropsch waxes can be converted into lubricating base oils with high viscosity index under hydroisomerization conditions, that is, GTL base oils, but compared with API Group II and III base oils, there is no significant advantage in low temperature performance , and the method of using deep hydroisomerization to improve low-temperature performance will lead to deepening of cracking and decrease of yield, so it is necessary to develop a process method for producing high value-added products

Description

technical field [0001] The invention relates to a continuous production method and device for lubricating oil base oil and / or solvent oil, in particular to a continuous production method and device for preparing lubricating oil base oil and / or solvent oil from Fischer-Tropsch synthetic oil. Background technique [0002] Under the reaction conditions of 150-350°C and 2.0-15.0MPa, the catalytic hydrogenation of CO by Fischer-Tropsch process can generate C 1 ~C 100 Range of gases, liquids, solid hydrocarbons. According to different fractions, it is mainly divided into Fischer-Tropsch synthetic light oil and Fischer-Tropsch wax. In today's situation of shortage of petroleum resources, the processing route of preparing liquid fuel or chemical products by Fischer-Tropsch synthesis has gradually gained support and achieved rapid development. Due to the big difference between Fischer-Tropsch synthetic oil and natural petroleum products, the economic benefits of the processing sch...
