Abstract
Catalysts in the form of cylindrical hollow granules, suitable for the dehydrogenation of ethylbenzene to styrene, and comprising, as active component, ferric oxide and promoters chosen among oxides of alkaline or alkaline-earth metals, oxides of elements of the lanthanide series, and chromium, tungsten, and molybdenum oxides, characterized by the absence of macroporosities with a radius of more than 50,000 .ANG. and/or by high mechanical characteristics of resistance to axial breaking and to abrasion.
