| description | The invention relates to a preparation method of a propane dehydrogenation Pt catalyst, which comprises the following steps: a MeOx-Al2O3 composite oxide carrier is prepared by a homogeneous precipitation method, Me is one or more of alkaline earth metal and transition metal, and the MeOx-Al2O3 carrier is of a spinel structure; the preparation method comprises the following steps: dipping an auxiliary agent X on a MeOx-Al2O3 carrier, and roasting X/MeOx-Al2O3; carrying out surface activation treatment on the X/MeOx-Al2O3 precursor carrier by adopting organic acid or H2O2; and loading an active component Pt on the X/MeOx-Al2O3 carrier with the activated surface by using a reduction-impregnation method to prepare the catalyst. According to the method, more dispersed metal Pt is obtained, meanwhile, the combination state of the metal Pt and the oxide carrier is regulated and controlled, the adsorption performance of Pt is changed, side reactions such as hydrogenolysis and carbon deposition are inhibited, and the |
