Catalysts for the production of alkenylaromatic compounds from alkylaromatic compounds, wherein the catalyst is mainly iron oxide, alkali metal compounds and up to about 100 ppm of precious metal sources such as palladium, platinum, ruthenium, rhenium, osmium, rhodium or iridium. Additional components of the catalyst can include compounds based on cerium, molybdenum, tungsten, chromium, calcium, magnesium, titanium and other such promoters. In addition, processes for producing alkenylaromatic compounds from alkylaromatic compounds using such catalysts, such as dehydrogenation of ethylbenzene to styrene. |
