Abstract
A process is provided for catalyst dehydrogenation of light paraffinic hydrocarbons using a catalyst comprising a noble metal and an intermediate pore size zeolite having a specified alkali content. The catalyst is sulfur tolerant, so that the dehydrogenation process can be carried out in the presence of sulfur or with periodic exposure to sulfur.
