Abstract
A catalyst for the dehydrogenation of C.sub.6 -C.sub.15 paraffins is disclosed. The catalyst contains, on support, at least one platinum group component, at least one promoter component from the group tin, germanium and lead, and at least one additional modifier. The additional modifier contains at least one alkaline earth metal. The stability of the catalyst is essentially higher than that achieved by conventional use of an alkali metal.
