Studies were made of the dehydrogenation of ethylbenzene to styrene on Al-,
Fe-, and Ga-containing as well as bare silica mesoporous materials of the
MSM-41 type. The optimum conditions for dehydrogenation on Fe- and Ga-conta
ining materials were determined by experimental design. It was found that t
he Fe-containing silicates are the most effective dehydrogenation catalysts
.
