Dehydrogenation catalyst and preparation method thereof

The invention discloses a dehydrogenation catalyst and a preparation method thereof. The dehydrogenation catalyst is a non-sulfurized catalyst and comprises an active component, chloride ions and a carrier, the active component at least contains noble metal components in the VIII family and accounts for 0.1-3% of the total weight of the dehydrogenation catalyst; the chloride ions account for 0.3-1.2% of the total weight of the dehydrogenation catalyst; the carrier is mainly gamma-Al2O3 (aluminum oxide). The dehydrogenation catalyst is wide in raw material source and suitable for large-scale industrial application. The catalyst is simple in composition and preparation process, and high low-temperature dehydrogenation activity and selectivity can be achieved under the condition that the loading amount of precious metal is very low. 本发明公开一种脱氢催化剂及其制备方法。该脱氢催化剂为非硫化型催化剂，该脱氢催化剂包含活性组分、氯离子和载体；所述活性组分至少含有第VIII族中的贵金属组分，占脱氢催化剂总重量的0.1～3％；所述氯离子占脱氢催化剂总重量的0.3～1.2％；所述载体主要为γ-Al2O3。本发明的脱氢催化剂原料来源广泛，适用于大规模工业应用。催化剂组成、制备流程简单，在贵金属负载量很
