Method for removing pyridine and homologues thereof as well as aniline and homologues thereof in phenolic products

The invention discloses a method for removing pyridine and homologues thereof as well as aniline and homologues thereof in a phenolic product, which comprises the following steps: removing pyridine and homologues thereof as well as aniline and homologues thereof in the phenolic product through a fixed bed filled with solid acid, the feeding flow rate of the phenolic product is 0.1-10BV/h, the adsorption temperature is 0-80 DEG C, and the pressure is normal pressure. According to the method, the pyridine and aniline alkaline nitrogen-containing compounds are selectively removed through solid acid chemical adsorption, on one hand, residues of pyridinium salt in crude phenol in a conventional acid pickling method are avoided, the quality of the crude phenol can be improved, and energy consumption in the crude phenol refining process is reduced; and on the other hand, the problems of large residual amount of strong acid in crude phenol, high salt-containing waste residue content in the crude phenol, serious equip
