Effect of diluent and reaction parameter on selective oxidation of propane over MoVTeNb catalyst using nanoflow catalytic reactor

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

“…The structure and surface of this catalyst have been described in more detail before [20]. The reproducibility of catalytic activity test has been carried out by repeated the Kinetic investigation of propane oxidation 275 experiments under the same condition and showed very good reproducibility in terms of both the propane conversion and acrylic acid selectivity [21].…”

“…This property of MoVTeNb is a key to the understanding of its function. Apparently, the specialised sites detected [20,21] for total oxidations are not very active and as shown in the kinetic survey study require a significantly higher thermal activation than the complex partial oxidation. The nanostructuring of the surface preventing large patches of such sites to be present may as atomistic origin hamper the combustion reaction requiring 10 oxygen atoms to be involved in the turnover of one propane molecule.…”

“…These preparations and the catalysts characterizations have been described in more detail before [20,21].…”

“…The effect of reactant concentration was studied at four different temperatures, i.e., 653, 663, 673, and 683 K. Particle size of catalytic material was 212-425 lm or less. The reaction was carried out in a nanoflow catalytic reactor [21]. For all experimental results, the reaction rate (rate of reactant disappearance and rate of products formation) and the concentration of reactants are calculated using Equations shown below:…”

KINETIC INVESTIGATION OF CARBON DIOXIDE, ACETIC ACID, ACRYLIC ACID FORMATION ON DILUTED AND LEACHED MoVTeNb CATALYST

“…The preparation of Diluted Mo 1 V 0.30 Te 0.23 Nb 0.125 O x and its characterization have been described in more detail before [8][9]. In addition, in this article the catalyst preparation is followed by leaching process using water for 1 h, and then it is dried and calcined according to the method described in the previous literature.…”
