HTFFR Kinetics Studies of A1 + CO2 Yields A10 + CO from 300 to 1800 K, a Non-Arrhenius Reaction.
Abstract
The previously described metal atom oxidation studies using a high-temperature fast-flow reactor (HTFFR) which, in its various modifications, allows the measurement of rate coefficients of reactions over roughly the 300-2000 K temperature range. The earlier HTFFR measurements covered most of this range for Al/O2 and AlO/O2 reactions. The rate coefficients of both these reactions were found to be, within experimental error, temperature independent. In the present work we have studied the reaction Al + CO2 gives AlO + CO. This reaction was selected since, on the basis of the most commonly accepted bond energy of AlO, it is endothermic and hence has an activation energy, i.e., a temperature-dependent rate coefficient. The reaction has indeed been found here to have a positive activation energy, though evidence is discussed suggesting it may be somewhat more energetic than usually assumed.
