“…This reaction exhibited obvious advantage compared to the oxidative dehydrogenation of ethane with O 2 , which had been demonstrated by many researchers [1][2][3][4]. Up to now, metal oxides [1,5], Cr-MSU-x [6], Cr/SBA-15/Al 2 O 3 /FeCrAl [7], Cr/SiO 2 [3,8], Ga/TiO 2 [9], Co-CaCO 3 [10], Cr/diamond [11], Cr/H-ZSM-5 [4], CaO-CeO 2 [2,12], Fe-Mn/Si-2 [13] and Mo 2 C/SiO 2 [14] have been used as catalysts for the dehydrogenation of ethane with CO 2 as an oxidant. Among these catalysts, Cr-based catalysts showed excellent performances for this reaction.…”

A series of Cr-Si-2 molecular sieves have been prepared by direct hydrothermal synthesis using tetrabutylammonium hydroxide as a template. Cr/Si-2 was also prepared by conventional impregnation. The synthesized materials were characterized by X-ray diffraction (XRD), N 2 adsorption (-196°C), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and diffuse reflectance (UV-vis) spectroscopic measurements. Cr-Si-2 sample with lower content of chromium (ca.

“…The various forms of Mo depend on the loading, support type, and catalyst preparation methods (Sattler et al, 2014). For example, in a Mo 2 C/SiO 2 system, by co-feeding CO 2 for the ODH reaction, the benefits of CO 2 in oxidizing the Mo 2 C forming Mo-oxycarbide at higher temperatures could be observed (Solymosi and Nemeth, 1999;Solymosi et al, 2001). In fact, Dury et al, 2003a) reported that dissociation of CO 2 on the catalyst surface could take place due to introduction of 3% CO 2 for the ODH reaction of propane over NiMoO 4 hence inducing the oxidation of molybdenum suboxide at temperatures around 673-723 K. The presence of both molybdates and molybdenum oxides can enhance the catalytic properties of NiMoO 4 in hydrocarbon oxidation (Lezla et al, 1997;Dury et al, 2003a).…”

This paper presents a review on the developments in catalyst technology for the reactions utilizing CO 2 for high-temperature applications. These include dehydrogenation of alkanes to olefins, the dehydrogenation of ethylbenzene to styrene, and finally CO 2 reforming of hydrocarbon feedstock (i.e., methane) and alcohols. Aspects on the various reaction pathways are also highlighted. The literature on the role of promoters and catalyst development is critically evaluated. Most of the reactions discussed in this review are exploited in industries and related to on-going processes, thus providing extensive data from literature. However, some reactions, such as CO 2 reforming of ethanol and glycerol, which have not reached industrial scale, are also reviewed owing to their great potential in terms of sustainability, which is essential as energy for the future. This review further illustrates the building-up of knowledge that shows the role of support and catalysts for each reaction and the underlying linkage between certain catalysts, which can be adapted for the multiple CO 2 -related reactions.

“…The main problem encountered in this reaction is catalyst deactivation due to carbon deposition and thus termination of syngas production. Up to date, Mo 2 C/SiO 2 [17], Cr/H-ZSM-5 [18,19], Cr/TS-1 [20], Cr/SiO 2 [15], Ga/TiO 2 [21], and CeO 2 -based oxides [22] have been used in the dehydrogenation of ethane with CO 2 as an oxidant. Among these catalysts, chromium-based catalysts have proven to be the most active for this reaction.…”

Selective Conversion of Ethane to Ethene via Oxidative Dehydrogenation Over Ca-doped ThO2 Using CO2 as Oxidant

2011

Ca-doped ThO 2 , synthesized by solution combustion method was tested for dehydrogenation of ethane with CO 2 . Doping ThO 2 with Ca resulted in the creation of oxide ion vacancies and an increased conversion of ethane compared to pure ThO 2 . On Th 0.75 Ca 0.25 O 2 selectivity to ethene was 97 at 46% ethane conversion at 725°C. Wellknown reference catalysts like 5%Cr/TS-1 or OMS-2 showed significantly lower selectivity, but the former was more active under the same conditions.
