ABSTRACT:
Low yield thermal cracking of a hydrocarbon such as ethylbenzene caused by contact with active metal surfaces in a catalytic dehydrogenation reactor is reduced by coating the metal surfaces, particularly those in the feed inlet end, with a thin layer of an inactivating metal or metal compound, such as V.sub.2 O.sub.5, preferably in an inert ceramic medium.
