The present invention discloses a method for separating oxygenates from Fischer-Tropsch oil. A gaseous boron halide is introduced into the Fischer-Tropsch oil to cause the boron halide to undergo a complexation reaction with the oxygenates in the Fischer-Tropsch oil, thereby forming a heterogeneous system of the oxygenate complex and the Fischer-Tropsch oil. The heterogeneous system is then separated to obtain a deoxygenated Fischer-Tropsch oil phase and an oxygenate complex phase. The boron halide pressure in the system is 0.05 to 1 MPa. By controlling the amount of boron halide added, the boron halide can be complexed with the oxygenates in the Fischer-Tropsch oil to separate the oxygenates from the oil, while preventing the boron halide from causing polymerization of olefins in the oil.
