Effects of reaction conditions on the selective oxidation of propane to acrylic acid on Mo–V–Te–Nb oxides

Effect of Drying on the Synthesis and Characterizationc MoVTeNbOx Mixed Metal Oxide Catalysts Prepared by Reflux

“…The main products detected are acrylic acid, propylene, carbon monoxide, carbon dioxide and acetic acid. The conversion of propane as a saturated hydrocarbon increases with temperature due to its low reactivity under lower reaction temperatures 12 .…”

Effect of pH on the Catalytic Properties of Mo–V–Te–P–O Catalysts for Selective Oxidation of Isobutane

“…However, a high effort will be done to understand the influence of the catalyst preparation procedure on the nature of crystalline phases formed in these multicomponent catalysts. In addition, effect of reaction conditions on the title reaction over the MoVTePO catalysts should be further investigated, since it has been reported that the external reaction conditions would have strong effects on the catalytic performance for propane oxidation over Mo-V-Te-Nb oxide catalysts [30]. Furthermore, reaction mechanism for isobutane oxidation over these Mo-V-Te-based , P = 101 kPa catalysts should be studied although some reasonable suggestions about reaction pathway have been proposed for the (amm)oxidation of propane [31,32].…”

Selective oxidation of propane over PMoVM/α‐Al2O3 (M: Co, Fe, or Ni)

“…• C. These reaction conditions to obtain acrolein are the same which are used in the propane oxidation to acrylic acid on Mo-V-(Te)(Nb) systems (Shishido et al, 2001;Botella et al, 2002Botella et al, , 2005Concepcion et al, 2004;Zhu et al, 2004;Baca et al, 2005;Corberân, 2005;Ueda et al, 2005). The decrease of propane conversion at 400…”

“…Most of the used catalysts in this reaction are mixed oxides constituted of several transition metal and nonmetal as such Mo-V-(Te)(Nb) selective to acrylic acid (Botella et al, 2002(Botella et al, , 2005Concepcion et al, 2004;Zhu et al, 2004;Baca et al, 2005;Ueda et al, 2005) and V-Sb-Mo (Shishido et al, 2001) and V-Sb-Bi-Ba/Mo-Bi-Co-Fe (Corberân, 2005) systems selective to acrolein. It has been also reported that the phosphovanadomolybdates of Keggin-type (HPA) were selective to acrylic acid in particular Cs 2.5 Fe 0.08 H 1.26 PMo 11 VO 40 (Mizuno et al, 1994(Mizuno et al, , 1995.…”

“…The techniques of preparation of mixed oxides are generally the hydrothermal synthesis or the sol-gel method (Botella et al, 2002(Botella et al, , 2005Concepcion et al, 2004;Zhu et al, 2004;Baca et al, 2005;Ueda et al, 2005). The inconveniences of these conventional methods are the use of high temperatures (600-700…”
