Catalyst for preparing arene from synthesis gas through one-step conversion and preparation method of catalyst

The invention relates to catalysts, in particular to a catalyst for preparing arene from synthesis gas through one-step conversion and a preparation method of the catalyst. The catalyst is prepared from, by mass, 30%-70% of zirconium-containing perovskite, 30%-60% of multistage porous zeolite molecular sieve and 0.1%-10% of oxide additive. The preparation method comprises the steps that 1, a salt compound of at least one of IA, IIA, VB, VIB, VIIB, IIB and IVA family elements and rare earth elements is weighed according to the components of the catalyst and added into water or alcohol to be prepared into a solution A; the multistage porous zeolite molecular sieve is weighed and added into the solution A, suction filtration, washing and filter cake drying are carried out to obtain solid powder, then the solid power and the zirconium-containing perovskite are mixed, ground and calcined, hydrogen or mixed gas of hydrogen and inert gases is introduced, heating is carried out for reduction, the reduced solid sample is tablet molded, and the catalyst is prepared.
