A catalyst for the production of alkenylaromatics from alkylaromatics, wherein the catalyst is predominantly iron oxide, an alkali metal compound and less than about 100 ppm of a source for a noble metal, such as palladium, platinum, ruthenium, rhenium, osmium, rhodium or iridium. Additional components of the catalyst may include compounds based on cerium, molybdenum, tungsten, chromium, calcium, magnesium, titanium and other such promoters. Also a process for the production of alkenylaromatics form alkylaromatics using this catalyst, for example the dehydrogenation of ethylbenzene to styrene. |
