“…This is the case for VPO [35][36][37][38] or pyridine exchanged molybdovanadophosphoric acid [39] catalysts, in which partial oxidation products, i.e., maleic anhydride or acrylic acid, were obtained during the oxidation of n-butane [35,39] or propane [36,39], respectively, while ethylene was mainly obtained during the oxidation of ethane on VPO [37][38][39]. However, it can be noted that the selectivity to ethylene obtained on MoVTeNbO catalysts is higher than that reported previously on VPO [35][36][37][38] or pyridine-exchanged molybdovanadophosphoric acid catalysts [39]. So, the most selective MoVTeNbO catalysts present a very low reactivity in the oxidation of ethylene.…”

“…[6] For smaller alkanes, this catalyst is much less efficient. [7] Therefore, lots of attention has been devoted to the search for improved vanadia-based catalysts for the ODH of ethane and propane. [8] Complementary research has focused on the geometric structure of supported vanadia catalysts and especially how structure can be related to catalytic performance.…”

“…60% at a butane conversion degree of 80% is actually obtained) [8]. However, this catalyst seems to be not so effective in the oxidative activation of C 2 -C 3 alkanes [9,10]. Table 1 shows comparatively the worldwide production of some of the most important olefins and partial oxidation products [11], being ethylene and acrylonitrile (ACN) the most important compounds as feedstock and chemical product, respectively.…”
