Dehydrogenation of Ethylbenzene

“…Numerous other catalysts based on zirconia were investigated by this group [95]. As another mild oxidant, N 2 O was used over alumina-supported transition metal oxides [99]. As another mild oxidant, N 2 O was used over alumina-supported transition metal oxides [99].…”

Oxidative dehydrogenation of ethylbenzene using nitrous oxide over vanadia–magnesia catalysts

“…There are some works reported in the literature on the use of nitrous oxide as a potential alternate mild oxidizing agent for ODH. 6,[17][18][19] Recently, N 2 O was used for the ODH of the lower alkanes, ethane and propane. Lo´pez Nieto et al 17 used N 2 O for the oxidative dehydrogenation of n-butane and found that selectivity to olefins was higher with N 2 O as the oxidant than with molecular oxygen.…”

“…Lo´pez Nieto et al 17 used N 2 O for the oxidative dehydrogenation of n-butane and found that selectivity to olefins was higher with N 2 O as the oxidant than with molecular oxygen. Kustrowski et al 18 studied the coupling of N 2 O decomposition with EB dehydrogenation and obtained promising results with respect to the EB and N 2 O conversions. N 2 O is also utilized for propane ODH with enhanced selectivity towards propene for the same degree of propane conversion compared to O 2 .…”

VOx supported SBA-15 catalysts for the oxidative dehydrogenation of ethylbenzene to styrene in the presence of N2O

“…The utilization of N 2 O is of additional interest as nitrous oxide has been recognized to be one of greenhouse gases causing global warning. Coupling the N 2 O decomposition with the ethylbenzene dehydrogenation over g-Al 2 O 3 -supported transition metal (Fe, Cr and Cu) oxide catalysts led to high conversions of EB and N 2 O [16]. Furthermore, a replacement of the alumina support by mesoporous silicas (SBA-15, MCF, MCM-48 and MSU) characterized by high surface area gave the Fe-, Cr-and Cu-containing catalysts, which were active in the oxidative dehydrogenation of EB in the presence of N 2 O [17].…”
