The invention discloses a preparation method of a catalyst for manufacturing propylene by disproportionating carbon four and ethylene. The preparation method mainly includes the steps: firstly, manufacturing a KIT-6 or P-doped KIT-6 carrier; secondly, dipping the carrier in rhenium soluble salt solution and tungsten soluble salt solution and then dipping the carrier in vanadium salt solution or niobium salt solution or tantalum salt solution by a stepwise dipping method; finally, drying, calcining and reducing the carrier to obtain the catalyst. Compared with an existing catalyst for manufacturing propylene by disproportionating carbon four and ethylene, the prepared catalyst has the advantages of high activity, low cost, long service life and environmental friendliness.
