Dehydrogenation catalyst as well as preparation method and application thereof

The invention relates to the field of catalysts, in particular to a dehydrogenation catalyst and a preparation method and application thereof. The dehydrogenation catalyst comprises a carrier, a noble metal active component and an auxiliary agent, the carrier is alpha-Al2O3 spheres, the active component is one or two of noble metals Pd and Pt, and the auxiliaries are a metal auxiliary and a rare earth element auxiliary; the metal additive is Cu or Mo, and the rare earth element additive is at least one of Y, Gd or Dy; wherein in terms of the weight of the carrier, the content of the active component is 0.08-0.13 wt%. According to the catalyst disclosed by the invention, the content of noble metal is reduced on the premise of ensuring the dehydrogenation precision and stability by selecting proper auxiliaries, so that the production cost of the dehydrogenation agent is reduced. 本发明涉及催化剂领域，具体涉及一种脱氢催化剂及其制备方法和应用。脱氢催化剂包括载体、贵金属活性组分以及助剂；所述载体为α-Al2O3球，活性组分为贵金属Pd、Pt中的一种或两种，助剂为金属助剂和稀土元素助剂；所述金属助剂为Cu或Mo，稀土元素助剂为Y、Gd或Dy中至少
