A method for separating oxygenated compounds from Fischer-Tropsch synthetic oil
By complexing the gaseous boron halide with the oxygen-containing compounds in the Fischer-Tropsch oil to form a heterogeneous system, combined with the steam stripping and thermal cracking methods, the problem of insufficient removal depth of oxygen-containing compounds in the Fischer-Tropsch oil was solved, and an efficient and economical separation effect was achieved.

AI Technical Summary
In the existing technology, the removal depth of oxygenated compounds in Fischer-Tropsch synthetic oil is not enough, the process is relatively long, and there are problems of high equipment cost and high energy consumption.
Gaseous boron halide is used to react with oxygen-containing compounds in Fischer-Tropsch synthetic oil to form a heterogeneous system, and the deoxygenated Fischer-Tropsch oil phase and the oxygen-containing complex phase are separated by steam stripping and thermal cracking. The boron halide can be recovered and reused.
The process achieves efficient and deep removal of oxygen-containing compounds, with the oxygen content in the product being less than 100 ppm and the deoxidation rate being ≥98%, thereby reducing separation costs and simplifying the process. The generated boron halide can be recycled and reused.
