COMPOSICAO CATALISADORA DE DESIDROGENACAO E PROCESSO PARA DESIDROGENAR UM COMPOSTO ALQUILAROMATICO

摘要

This invention relates to an improved dehydrogenation catalyst, useful in converting alkylaromatics to alkenylaromatics, e.g. ethylbenzene to styrene, which contains lower amounts of iron and relatively larger amounts of cerium and potassium than those known to the art.
