Temperature Dependence of the Kinetics of Elementary Combustion Reactions of Refractory Species

摘要

The dependence of the rate coefficients of gas-phase reactions of monatomic and diatomic refractory species on temperature is discussed. Examples given pertain primarily to Aluminum and Boron species reactions in the 300-1900 K range. These reactions show a wide variety of In k(T) vs. T-l behavior patterns. It is shown that, because of this variety, it is not yet possible to make reliable predictions regarding reactions for which no experimental data on temperature dependence are available. However, some guidance is given toward making preliminary estimates. Quantitative kinetic data on the reactions are given and the importance of their thermochemistry is discussed. The experimental method (HTFFR) used to obtain these data is briefly reviewed.
