The invention discloses a catalyst, which is carried by an AlSn-SBA-15 molecular sieve with SnAl double metal-containing framework, for dehydrogenation of propane for preparing propylene. In the catalyst, the AlSn-SBA-15 molecular sieve with SnAl double metal-containing framework is used as a carrier, platinum-group element metal is used as a main catalyst, IVA-group, IA-group or IIA-group element metal is used as an auxiliary agent, and high-temperature-resistant inorganic oxide is used for forming an adhesive. A multi-step dipping method is used in the preparation of the catalyst, namely the alkaline metal auxiliary agent is dipped, so that the acidity and alkalinity of the catalyst and the types of cations in pores of the molecular sieve are effectively modulated by cation exchange technology, and the platinum-group element metal is dipped. The catalyst has superior anti-carbon deposit performance, high propane conversion rate under the reaction conditions of high temperature and low pressure, propylene selectivity and reaction stability.
