Kinetics of Diesel Nanoparticle Oxidation
Environmental Science & Technology, 2003The technique of high-temperature oxidation tandem differential mobility analysis has been applied to the study of diesel nanoparticle oxidation. The oxidation rates in air of diesel nanoparticles sampled directly from the exhaust stream of a medium-duty diesel engine were measured over the temperature range of 800-1140 degrees C using online aerosol ...

KINETICS AND MODELING OF BENZENE OXIDATION
Chemical Engineering Communications, 1982The gas phase oxidation of benzene over a V2O5 + P2O5 + MoO3 + Sb2O3 catalyst supported on kieselguhr carrier is studied at the temperature range 344–393°C. 14 different kinetic models are tried to determine the mechanism of benzene oxidation. It is shown that benzene oxidation takes place via a two step redox mechanism which is first order with ...

Calcium oxide carbonization kinetics
Bulletin of the Russian Academy of Sciences: Physics, 2009The amount of associated carbon dioxide is found to depend on the technique of CaO pretreatment. Distended imperfect surface layers of the oxide prepared in a jar mill are more reactive in comparison with the oxide that was not subjected to any mechanical treatment.

Kinetics of Biological Oxidation
Water Quality Research Journal, 1966Abstract The future development of the activated sludge process depends to a large extent upon a basic understanding of the kinetics of the biological processes involved and an evaluation of the effects of various factors on these kinetics. A realistic evaluation of the effects of such variables as influent quality and quantity, presence

To supplement previous ignition delay investigations on methane-oxygen-argon mixtures, product distributions were determined for methane-oxygen-argon and methane-hydrogen-oxygen-argon mixtures that had been heated in a single-pulse shock tube. On the basis of these combined data and literature values, extensive kinetic calculations, involving numerical

AbstractEthane oxidation in jet‐stirred reactor has recently been investigated at high temperature (800–1200 K) in the pressure range 1–10 atm and molecular species (H2, CO, CO2, CH4, C2H2, C2H4, C2H6) concentration profiles were obtained by probe sampling and GC analysis.

The recently developed interest in boron as a possible component of mixed fuels makes it appropriate to study the oxidation kinetics of boron. Based on experimental data on the oxidation of boron at temperatures of up to 1000~ the authors of [i, 2] have obtained a parabolic oxidation law.

Abstract : The present work provides kinetic information on Al oxide reactions. To measure such kinetics the authors have modified the AeroChem high- temperature fast-flow reactor to allow direct observation of AlO by laser induced resonance fluorescence. They report here on the experimental methods and on their first observations on the reaction AlO +

The properties of surface films on pyrite have been studied through electrochemical techniques of cyclic voltammetry and AC impedance measurements. The characteristics of the surface films depend on the conditions of oxidation and the source of pyrite.

Phase-field model of oxidation: Kinetics
Physical Review E, 2020The kinetics of oxidation is examined using a phase-field model of electrochemistry when the oxide film is smaller than the Debye length. As a test of the model, the phase-field approach recovers the results of classical Wagner diffusion-controlled oxide growth when the interfacial mobility of the oxide-metal interface is large and the films are much ...
