Thiocyanate Bio-oxidation Kinetics

Journal of the Environmental Engineering Division, 1981
Thiocyanates have been found in most coal conversion and coke plant effluents. Data were developed for the biological degradation rate kinetics of thiocyanate removal, and material balance information was developed for the fate of sulfur and nitrogen resulting from such bio-decomposition of aqueous thiocyanates.

Kinetics of vanillin oxidation

Chemical Engineering & Technology, 1996
AbstractVanillin can be produced by oxidation of kraft lignin, with air, in alkaline medium. The optimal conditions for vanillin production strongly depend on pH and temperature. This paper addresses the effect of temperature and pH on vanillin degradation by oxidation.

AEROSOL GROWTH KINETICS DURING SO2 OXIDATION

Atmospheric Environment (1967), 1978
Abstract Consideration is given to the water vapor/sulfuric acid mixture and, after discussing the theoretical results obtained by various authors, they are applied to the case of the atmospheric conditions after having introduced the notion of heteromolecular condensation.

Kinetics of Sicl4 Oxidation

Journal of the American Ceramic Society, 1978
The oxidation rate of SiCl 4 was studied at 1100° to 1300°C. The reaction was first order in SiCl 4 and zero order in O 2 up to a 20‐fold excess of O 2 . At higher O

Oxidation Kinetics of Palladium

2020
The kinetics of oxidation of palladium is investigated in this study. The effects of temperature and pressure on the oxide growth of palladium are discussed. A study of the linear regime of palladium oxidation data is examined, and regression analysis is utilized to analyze the oxidation of palladium.

Global interinsic kinetics of wood oxidation

Fuel, 2004
Weight loss curves of two wood species (beech and Douglas fir) have been measured in air for four heating rates between 5-40 K/min and a final temperature of 873 K. A four-step series mechanism describes well the details of the thermogravimetric curves of the devolatilization/combustion process.

Kinetics of ethane oxidation on vanadium oxide

The Journal of Physical Chemistry, 1990
The oxidation of ethane with molecular oxygen on a well-characterized V{sub 2}O{sub 5}/SiO{sub 2} catalyst produced ethylene and acetaldehyde as the only selective oxidation products. The effects of partial pressures of ethane, oxygen, and water were investigated at 841 K, and it was found that only water had a strong influence on the overall ...

Carbon monoxide oxidation kinetics on zinc oxide

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1988
The oxidation of carbon monoxide on zinc oxide obeys first-order kinetics for CO and zero-order kinetics for O2 with an activation energy of 104 J mol–1 at temperatures in the range 190–250 °C. The apparent kinetics have been characterised as the sum of two different reaction paths (I and II), using the transient response method.

Kinetics of the Oxidation of Triphenylphosphine by Nitric Oxide

Inorganic Chemistry, 2002
The oxidation of PPh3 by NO to N2O and Ph3PO in homogeneous solution occurs by third-order kinetics, d[Ph3P]/dt = k3[Ph3P][NO]2; analysis of solvent and substituent effects suggests formation of a phosphonium diazeniumdiolate intermediate prior to oxygen transfer from nitrogen to phosphorus.
