“…The O 2 to n-heptane molar ratio of 1.4 was lower than the ratio of 2.5 in autothermal reforming. Carbon dioxide was fed in three-fold stoichiometric excess with the CO 2 to n-heptane molar ratio of 21 in order to reduce the catalyst deactivation by coking [9]. The amount of the catalysts was 0.1 g and the total feed rate was 1 dm n 3 min À1 .…”

“…Pt metals are active catalysts for C 2 H 6 + CO 2 reaction, but at higher temperatures instead of dehydrogenation of ethane its dry-reforming becomes the dominant process. Rh/ZSM-5 presents a good example for this feature [13]. On the less reactive Mo 2 C/SiO 2 [14], the selectivity of ethylene formation was 90-95% at an ethane conversion of 30%.…”

“…In this case, however, we may count with the undesired oxidation of C x H y species. This side reaction can be minimized by using CO 2 as a mild oxidant [11][12][13][14][15][16][17]. Pt metals are active catalysts for C 2 H 6 + CO 2 reaction, but at higher temperatures instead of dehydrogenation of ethane its dry-reforming becomes the dominant process.…”

Reaction of C 2 H 6 with CO 2 Au catalyst Effects of supports Electronic interaction between Au and oxides a b s t r a c tThe dehydrogenation of C 2 H 6 and its reaction with CO 2 have been investigated on Au deposited on various oxides. Both reactions occurred at relatively high temperatures, above 650 K. Ethylene formed in the dehydrogenation process with high selectivity, 94-98%, on most of the catalysts. The conversion of C 2 H 6 varied with the nature of support and fell in the range of 3-19%. Adding CO 2 to C 2 H 6 only slightly influenced the reaction of C 2 H 6 on Au/MgO and Au/Al 2 O 3 , but markedly increased the conversion of C 2 H 6 and changed its reaction pathways on Au deposited on n-type TiO 2 , CeO 2 and ZnO. Taking into account the properties of these oxides, we came to the conclusion that their electric behavior and not their defect structure play a dominant role in the enhanced activity of Au deposited on these supports. Based on the different work functions, an electronic interaction between Au particles and these oxides is proposed, which facilitates the formation of reactive negatively charged CO 2 .

“…There is a great variety in the reactivity of alkanes. Whereas both the decomposition and dry reforming of CH 4 requires high temperature even on the most active Rh [4,5], the reactions of C 2 H 6 [6e8] and C 3 H 8 [9,10] proceeds at significantly lower temperatures. This difference in the reactivity appeared in their aromatization on Mo 2 C/ZSM-5.…”
