FIELD: chemistry.
SUBSTANCE: method of producing styrene through dehydrogenation of ethylbenzene involves bringing material into contact with an iron-based dehydrogenation catalyst under dehydrogenation conditions, where the said catalyst contains titanium in concentration ranging from 1 ppmw to 1000 ppmw, where the said material contains ethylbenzene and vapour, and vapour is in such an amount which ensures molar ratio of vapour/hydrocarbon in the said material not greater than 9:1. The invention also relates to a method of improving operation of the device for producing styrene from ethylbenzene which uses a catalyst containing the same amount of titanium as the above described catalyst, as well as a similar molar ratio of vapour/hydrocarbon in the material.
EFFECT: improved dehydrogenation process.
