The invention belongs to the technical field of chemical engineering, and particularly relates to an acetylene trimerization benzene preparation catalyst, and a preparation method and application thereof. The acetylene trimerization benzene preparation catalyst is a supported catalyst taking an ordered mesoporous material as a carrier; the catalyst is prepared from the following ingredients in parts by weight: 0.1 to 3 weight parts of bis(acetonitrile)palladium(II) chloride, 25 to 70 weight parts of cuprous chloride and 27 to 75 weight parts of acid salt. By using the supported catalyst taking the ordered mesoporous material as the carrier, acetylene can be catalyzed to generate cyclotrimerization reaction to generate benzene; in the reaction process, the conversion rate of the acetylene and the selectivity of benzene are high; the service life of the catalyst can maintain a long time; the catalyst is applicable to industrialized amplification production, and has good market application prospects. 本发明属于化工技术领域
