the increasing use of styrene, for the production of thermoplastics and rubbers, has given a special importance to this vital materialin petrochemical industries. more than 95 per cent of styrene production in the world is by dehydrogenation of ethylbenzene. present styrene production units are basically designed on the basis of 1940s units. producing countries and related research centres have...

Our study focuses on the structural evolution of MCM-41-supported iron oxide under the reducing environment of catalyst pretreatment and ethylbenzene dehydrogenation reaction. Powder X-ray diffraction (XRD) analysis showed that the iron oxide is well-dispersed on the surface of the support with no detectable diffraction peaks from iron oxide. X-ray absorption near edge structure (XANES) study i...

Oxidative dehydrogenation (ODH) is an alternative for styrene (ST) production compared to the direct process. However, ODH with O2 or CO2 suffers from either over-oxidation endothermic property/low ethylbenzene conversion. Herein, we proposed process a CO2-O2 mixture atmosphere efficient conversion of (EB) into styrene. A thermoneutral possible by rationalizing CO2/O2 molar ratios 0.65 0.66 in ...
