Abstract

A method of analysis that enables the determination of further chemical time scales for ignition and a time scale for pyrolysis has been developed. The concept is based on the correlation of species concentration such as the fuel with another species that is formed during ignition or pyrolysis. The problem with this method is the difficulty or indirect approach associated with fuel concentration measurement. It turns out that we can make use of the measurement of a chosen intermediate such as CO during oxidation and pyrolysis of biofuels to evaluate this function. CO concentration time histories behind the reflected shock during ignition and pyrolysis of propanol isomers are measured by mid-infrared laser absorption using quantum-cascade laser near 4.6 m. Determination of these time scales enable us to distinguish between the kinetics of oxidation and pyrolysis while also delineating conditions under which one is more significant than the other.
