The catalytic performance of MoVMnW mixed oxides was investigated in the oxidative dehydrogenation of ethane at three different reaction temperatures (235, 255, and 275 ∘ C) using oxygen as an oxidant. The catalysts were characterized by using X-ray diffraction, temperature-programmed reduction, and scanning electron microscopy. The MoVMnW mixed oxide catalyst showed the 70-90% of ethylene selectivity at the reaction temperatures. However, a significant decrease in the selectivity of ethylene was observed by increasing the reaction temperature from 235 ∘ C to 275 ∘ C.

“…Due to the importance of the redox properties of catalysts in selective oxidation of isobutane, V and Mo are always combined together in the catalyst as the redox reaction occurs: V 5+ + Mo 5+ → V 4+ + Mo 6+ . Guan et al [76] prepared a series of Mo-V-O catalysts by varying the V/Mo molar ratio. It was found that the catalyst with a V/Mo ratio of 0.3 achieved the best MAC selectivity (40.4%) at an isobutane conversion of 6.4%.…”

Selective oxidation of isobutane to methacrolein (MAC) and methacrylic acid (MAA) has received great interest both in the chemical industry and in academic research. The advantages of this reaction originate not only from the low cost of the starting material and reduced process complexity, but also from limiting the use of toxic reactants and the production of wastes. Successive studies and reports have shown that heteropolycompounds (HPCs) with Keggin structure (under the form of partially neutralized acids with increased stability) can selectively convert isobutane to MAA and MAC due to their strong and tunable acidity and redox properties. This review hence aims to discuss the Keggin-type HPCs that have been used in recent years to catalyze the oxidation of isobutane to MAA and MAC, and to review alternative metal oxides with proper redox properties for the same reaction. In addition, the influence of the main reaction conditions will be discussed.

“…Then, they studied the kinetics of isobutane selective oxidation over Mo-V-P. Guan et al take Mo-V-Te as the catalyst for isobutane selective oxidation to MAL/MAA, the total yield can be 7.1% [7]. Afterward, they introduce the P into Mo-V-Te and the total selectivity of MAL/MAA is up to 68 wt% when the reaction temperature is 400 oC [8]. Pual et al applied kegging-type polyoxometalates in this process, but the stability was poor [9].…”

Acetone, a widely used chemical raw material, is synthesized by the cumene peroxide method. At present, the cumene peroxide method has the disadvantage of high raw material cost, low flexibility, and complex process. Isobutane as an important C4 resource is mainly used as liquefied gas, which is a waste of fossil resources. Based on that, a novel acetone synthesis method from isobutane with the intermediate of di-tert-butyl peroxide (DTBP) is proposed. The reaction performance of TiO2-S and the optimal reaction condition for isobutane selective oxidation to DTBP is evaluated, and the selectivity to DTBP is 30 wt%. Then, the ZSM-5 is proved as the optimal catalyst for DTBP decomposition and the acetone selectivity is 38 wt% under the optimal reaction condition. In general, isobutane selective oxidation to DTBP which is further catalytic decomposition to acetone is feasible.
