The synthesis of acrolein and acrylic acid by direct propane oxidation with Ni–Mo–Te–P–O catalysts

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

“…It has been known [7,8] By using PCPDFWin software, the peak at 2θ = 22.1 • can be related to the presence of several Mo-containing phases, i.e., (V 0.07 Mo 0.93 ) 5 ] (M = Mo, V) having orthorhombic and hexagonal structure, respectively, and the orthorhombic M1 phase is the most active and selective phase for propane oxidation, a synergism due to cooperation between M1 and M2 phases improves the catalyst performance.…”

“…5, it can be seen that acrylic acid has already been formed even in steam-free condition, which indicates that steam is important but not the indispensable for the formation of acrylic acid. The most possible reason for the positive effect is that steam enhances the desorption of the strongly adsorbed acrylic acid on the catalyst surface to prevent it from overoxidation to CO x [5,19,20].…”

“…By now, three classes of catalyst systems, VPO-type catalysts [1,2], heteropoly compounds catalysts (HPC) [3,4] and multi-component metal oxides catalysts (MMO) [5][6][7][8][9][10], have been studied for the selective oxidation of propane to acrylic acid. MMO catalysts are commonly considered to have a possibility to substitute the traditional catalysts in the existing industrial two-step process via propylene.…”

Kinetic investigation of propane oxidation on diluted Mo1–V0.3–Te0.23–Nb0.125–O x mixed-oxide catalysts

“…Significant differences in the reaction pathways are observed when the reaction is carried out over, Te-P/NiMoO catalysts [19], Mo-V-Sb-Nb catalysts [10], and Mo-V-Te-Nb catalysts [9]. This article deals with the reaction kinetics and mechanism of propane partial oxidation to acrylic acid on diluted MoVTeNbOx mixed-oxide catalysts using high-throughput system (nanoflow reactor).…”

AgBiVMo oxide catalytic membrane for selective oxidation of propane to acrolein

“…In order to achieve high selectivity to acrolein for the selective oxidation of propane, researchers have devoted a lot of work to screening different kinds of catalysts to find one with high selectivity [1][2][3][4][5][6][7][8][9][10][11][12][13]. Among these catalysts, Ag 0.01 Bi 0.85 V 0.54 Mo 0.45 O 4 is a good one for the selective oxidation of propane to acrolein.…”
