Abstract
In this work we investigate by numerical methods, the autoignition temperature of lean mixtures of n-butane in air, and show how it varies within a range of temperatures and compositions. We show that relatively small increases of pressure above atmospheric, of even rather lean mixtures, can autoignite at 550 K. The primary results are evaluated with respect to published experimental studies. The kinetic foundation is then analysed by formal numerical methods to trace the origins of the dramatic shifts in autoignition temperatures as conditions are changed. The most important reactions leading to hydrogen peroxide formation are identified using rate of production analysis, and the greatest heat releasing reactions are determined in the transition from cool flame to ignition.
