Dynamic methods for catalytic kinetics

Toluene oxidation over ZrO2-based gasification gas clean-up catalysts: Part B. Kinetic modeling

“…Additionally, when applying the temperature-programmed techniques, data for kinetic modeling can be collected with a moderate number of experiments, thus considerably accelerating the work of catalyst testing [14,15]. Three different modes of temperature-programmed techniques have been applied for kinetic modeling: the desorption of an adsorbed component (TPD, e.g.…”

Insights into the Reactivity of La1−x Sr x MnO3 (x = 0 ÷ 0.7) in High Temperature N2O Decomposition

“…Assuming that the sample particles have a spherical form, their characteristic size r = 3 V/S = 3 q Á S BET & 1.6 9 10 -7 m and D e & 10 -3 m 2 /s, the value of s in can be estimated as 10 -10 s (where r-particle radius (m), V-characteristic volume calculated from the theoretical density (m 3 ), S-characteristic surface of the particle (m 2 ), q-real density of catalyst (g/m 3 ), S BET -BET surface area (m 2 /g)). This value certainly satisfies the criterion of the absence of the reaction limitation by diffusion in the pores [11]. Table 1 summarizes data on phase composition of the La 1-x Sr x MnO 3 catalysts and structural parameters of detected phases.…”

Selective catalytic reduction of NO in a reverse-flow reactor: Modelling and experimental validation

“…and is being actively studied [3][4][5][6][7]. NO x emissions can be reduced by decreasing NO x formation (primary strategies, e.g.…”
