“…The kinetics of the MIBK combustion process is rather poorly known. As already stated, to our knowledge, the only published work investigating the kinetics of MIBK combustion over a Pt/ γ ‐Al 2 O 3 catalyst is the paper of Tseng et al 13. The authors concluded that the models based on the Mars–van Krevelen and LH theories are suitable to describe the kinetics of MIBK combustion over Pt/ γ ‐Al 2 O 3 .…”

“…The authors concluded that the models based on the Mars–van Krevelen and LH theories are suitable to describe the kinetics of MIBK combustion over Pt/ γ ‐Al 2 O 3 . We tested the kinetic expressions developed by Tseng et al 13 using their original parameter values, but none of them satisfactorily fitted our experimental light‐off curves. Therefore, we developed a kinetics modeling study, which is presented in the next section.…”

“…Tseng et al. 12, 13 treated diluted mixtures of MIBK in air over a commercial Pt/ γ ‐Al 2 O 3 catalyst in a fixed‐bed reactor. The results showed that, under incomplete combustion conditions, carbon monoxide and acetone predominated among the oxidation intermediates.…”

“…The authors suggested that a deactivation effect may be induced by coking on the catalyst surface, the phenomenon of carbon coating being more obvious at relatively low temperatures (423 K) than at higher ones (573 K). To the best of our knowledge, the only kinetic study regarding the MIBK kinetics over the Pt/ γ ‐Al 2 O 3 catalyst is that of Tseng et al 12, 13, based on the LH model. However, the authors do not specify the Pt concentration in the catalyst, they do not give the maximum MIBK conversion they used in the differential type experiments, and the tests of the proposed rate expression on the integral type experiments were not very conclusive.…”

Catalytic combustion of methyl isobutyl ketone (MIBK) in diluted air mixtures over a commercial Pt/Al 2 O 3 catalyst was experimentally investigated in a continuous laboratory setup. The experimental data were used to develop a kinetic model of the MIBK combustion over the Pt/Al 2 O 3 catalyst. Among the available kinetic theories, the Langmuir-Hinshelwood one proved to be the most appropriate for the obtained data. The kinetic parameters of the formulated rate expression were estimated using both differential and integral methods. The adequacy of the proposed kinetic model and the estimated parameter values were tested by statistical criteria and thermodynamic consistency. The computation results indicate that the integral method, based on a heterogeneous reactor model, is the recommended approach in the estimation of the kinetic parameters for catalytic combustion processes involving volatile organic compounds.

“…To study the oxidation kinetics expressions involving surface interactions and competitive adsorption of NH 3 over nanoscale copper-cerium bimetallic catalyst with highly active, three kinetic models: power-rate law model, Mars and van Krevelen model, and Langmuir-Hinshelwood model were examined [25][26][27]. These approaches will be adopted in the next section in this paper.…”

Catalytic combustion kinetics of isopropanol over novel porous microfibrous‐structured ZSM‐5 coating/PSSF catalyst

Porous thin-sheet cobalt-copper-manganese mixed oxides modified microfibrous-structured ZSM-5 coating/PSSF catalysts were developed by the papermaking/sintering process, secondary growth process, and incipient wetness impregnating method. Paper-like sintered stainless steel fibers (PSSF) support with sinter-locked three-dimensional networks was built by the papermaking/sintering process, and ZSM-5 coatings were fabricated on the surface of stainless steel fibers by the secondary growth process. Catalytic combustion performances of isopropanol at different concentrations over the microfibrous-structured Co-Cu-Mn (1:1:1)/ZSM-5 coating/PSSF catalysts were measured to obtain kinetics data. The catalytic combustion kinetics was investigated using power-rate law model and Mars-Van Krevelen model. It was found that the Mars-Van Krevelen model provided fairly good fits to the kinetic data. The catalytic combustion reaction occurred by interaction between isopropanol molecule and oxygen-rich centers of modified microfibrous-structured ZSM-5 coating/PSSF catalyst. The reaction activation energies for the reduction and oxidation steps are 60.3 and 57.19 kJ/mol, respectively.
