摘要： The present invention relates to a method of preparing an aromatic compound from acetylene, which includes synthesizing an aromatic compound from an acetylene-containing reactant gas in the presence of a zeolite catalyst for the aromatization of acetylene, and subjecting the zeolite catalyst deactivated by the coke formed in the aromatization of acetylene, to plasma treatment at ambient temperature and pressure so as to selectively remove the external cokes and partial internal coke, thereby regenerating the zeolite catalyst; a method of regenerating the zeolite catalyst used in the aromatization of acetylene by plasma treatment; and a regenerated zeolite catalyst for the aromatization of acetylene, prepared thereof.
