A catalyst for propane dehydrogenation to propylene and its preparation method and application
The invention discloses a catalyst for propane dehydrogenation to propylene and a preparation method and application thereof. The catalyst comprises a support, an active component and promoters supported on the carrier. Among them, the carrier is alumina ball, the active component is platinum group metal, the promoters include three kinds: rare earth elements (Y, La, Ce, Pr, Nd), tin, and alkali metal elements (Li, Na, K). When the catalyst is used for propane dehydrogenation to propylene, higher propane conversion and propylene selectivity are obtained.
