Acetylene Oxidation in a JSR From 1 to 10 Atm and Comprehensive Kinetic Modeling

An experimental and modeling study of the oxidation of acetylene in a flow reactor

“…6 shows an example, for the conditions of set 1 of Table 1, of the impact of varying the reaction rate on the interaction of C 2 H 2 with O 2 . Solid lines show the present mechanism and dashed lines show the present mechanism with the reaction rate proposed by Laskin and Wang [5] for the C 2 H 2 + O 2 interaction, 4.60 × 10 15 (cm 3 /(mol s))T −0.54 e (−4470 cal/RT ) , independent of the product channels chosen for simulation (reactions (2) to (5)). As seen in Fig.…”

“…The decision of choosing HCO as the only reaction product for this reaction should be taken cautiously, because as mentioned in Section 3, other different product channels and reaction rates have been proposed in the literature (e.g., reactions (2) to ( and Bozzelli [10]. The results are only sensitive to the global rate of acetylene conversion by interaction with O 2 and not to the product channel chosen.…”

“…It is an intermediate species during combustion processes and it is recognized as one of example, in Skjøth-Rasmussen et al [1]). Among the different studies addressing the conversion of acetylene from both experimental and kinetic modeling points of view, we can mention as an example the work of acetylene oxidation in a jet-stirred reactor of Tan et al [2], a number of works based on shock tube reactors, such as the works of Hidaka et al [3], Ryu et al [4], Laskin and Wang [5], Fournet et al [6], Varatharajan and Williams [7], or Eiteneer and Frenklach [8], and the works considering flames, such as those of Leung and Lindstedt [9] and Sheng and Bozzelli [10]. Even though acetylene oxidation has been addressed quite extensively, significant uncertainties still remain in relation to the kinetic modeling of the process and specifically to various reaction pathways and rates important for the conversion of acetylene.…”

Oxidation of H2/CO2 mixtures and effect of hydrogen initial concentration on the combustion of CH4 and CH4/CO2 mixtures: Experiments and modeling

“…The JSR experimental set-up used here was presented previously [4][5][6][7][8]. It consisted of a 30 cm 3 fused-silica sphere, to minimize wall catalytic reactions, equipped with four nozzles of 1 mm ID for the admission of the gases providing the stirring.…”

The oxidation of a diesel fuel at 1–10 atm: Experimental study in a JSR and detailed chemical kinetic modeling

“…The rates of reaction were computed from the kinetic reaction mechanism and the rate constants calculated at the experimental temperature. The rate constants for the reverse reactions were computed from the forward rate constants and the appropriate equilibrium constants [7][8][9] The oxidation mechanism for the diesel fuel was obtained by merging the individual oxidation mechanisms validated for the oxidation of n-hexadecane [10,11], iso-octane [10,11], n-propylcyclohexane [10,11], n-propylbenzene [10,11], and 1-methylnaphtalene [11]. The pressure dependencies of reactions were taken into account and updated [11].…”
