FIELD: hydrogenation-dehydrogenation catalysts.
SUBSTANCE: invention provides catalyst based on iron oxide and lanthanide compound wherein at least part of iron oxide is prepared via a method including thermal decomposition of iron halide and which contains lanthanide in amount corresponding to 0.07 to 0.15 mole per mole iron oxide found in catalyst (calculated as Fe2O3). A catalyst is also described wherein part of iron oxide contains residual halide. Preparation of catalyst involves providing a mixture containing sufficient amounts of at least iron oxide and lanthanide compound followed by calcination of the mixture. Alkylaromatic compound dehydrogenation process is further described involving contact of raw feed containing alkylaromatic compound with above-described catalyst as well as polymer or copolymer production process involving production of alkenylaromatic compound as described above and subsequent polymerization thereof or copolymerization with a monomer.
EFFECT: enabled production of alkenylaromatic compounds with improved characteristics owing de decreased formation of by-products.
