This invention relates to a process for the production of styrene monomer by the dehydrogenation or oxidative dehydrogenation of ethylbenzene in the presence of recycle gas and more particularly to a method of reducing the boiling point of liquid ethylbenzene feed in the production of styrene monomer. The process comprises the step of catalytically dehydrogenating or oxydehydrogenating ethylbenzene in the presence of a mixture, wherein the mixture substantially comprises carbon dioxide, thereby catalytically producing styrene monomer.
La présente invention concerne un procédé de production de monomère de styrène par déshydrogénation ou déshydrogénation oxydante déthylbenzène en présence de gaz recyclé et plus particulièrement un procédé permettant de réduire le point débullition dune charge déthylbenzène liquide dans la production de monomère de styrène. Le procédé comprend létape consistant à déshydrogéner ou oxydéshydrogéner catalytiquement léthylbenzène en présence dun mélange, le mélange comprenant sensiblement du dioxyde de carbone, de ce fait produisant catalytiquement un monomère de styrène.
