CATALYSTS AND PROCESS FOR CATALYTICALLY CONVERTING NAPHTHA TO LIGHT OLEFINS

Abstract: a zeolitic catalyst and a process for its use is provided where the metal, preferably platinum, on the catalyst is not well dispersed as shown by low levels of h2 chemisorption, and low chemisorption hydrogen to platinum ratios. in a process for converting naphtha to light olefins that comprises contacting a naphtha stream with a zeolitic catalyst to produce a light paraffin stream at conditions which dehydrogenate the naphtha to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefins to produce a light paraffin stream comprising ethane and propane, this catalyst produces a higher proportion of ethane.
