Abstract (en)
[origin: WO0241990A1] This invention relates to a layered catalyst composition, a process for preparing the composition and processes for using the composition. The catalyst composition comprises an inner core such as alpha-alumina, and an outer layer bonded to the inner core composed of an outer refractory inorganic oxide such as gamma-alumina. The outer layer optionally has uniformly dispersed thereon a platinum group metal such as platinum and a promoter metal such as tin. The composition also optionally contains a modifier metal such as lithium. The catalyst composition shows improved durability and selectively for dehydrogenating hydrocarbons.
