The invention discloses a separation method for alkali nitrogen compounds in coal liquefaction oil. The separation method comprises the following steps of: acid pickling: mixing the coal liquefaction oil with an acidic solution, carrying out vibrating, standing and layering, and separating to obtain a water phase solution; and organic solvent extraction: regulating the pH value of the water phase solution to be 8-10, adding organic solvents after cooling, carrying out mixing, vibrating, standing and layering, and separating to obtain an organic phase solution rich in the alkali nitrogen compounds. By utilizing the separation method disclosed by the invention, the alkali nitrogen compounds in the coal liquefaction oil are processed by utilizing an acid pickling method and an organic solvent extraction method, the effects that the alkali nitrogen compounds in the coal liquefaction oil are good in separation selectivity and high in separation degree and are thoroughly extracted are achieved, and the obtained organic phase solution can be directly used for carrying out sample injection analysis on the alkali nitrogen compounds.
