The majority of industrial production of styrene based on from the dehydrogenation of ethylbenzene. This dehydrogenation process involves the catalytic reaction of ethylbenzene. This process involves a highly endothermic reaction carried out in the vapor phase over a solid catalyst.
Rezel-EDH catalysts showed high activity and good selectivity in commercial application.
Rezel-EDH-1 decreased the reaction temperature by 2-5 ℃, Rezel-EDH-2 extend a life time for 30 months and Rezel-EDH-3 increased the space velocity by 5-10%.
