dc.description.abstractPentane isomers are important constituents of distillate gasoline, compressed natural gas and liquefied petroleum gas. Pentane chemistry is integral component of the chemical kinetic mechanisms of larger hydrocarbons. Existing kinetic mechanisms differ in their predictions of the oxidative and pyrolysis behavior of pentane isomers. This work provides new species time-history data to validate and improve pentane chemistry models. Methane, acetylene and ethylene are measured during the high-temperature pyrolysis of n-pentane and iso-pentane. Experiments are performed behind reflected shock waves over 1400–2100 K and pressures near 1 atm. Methane and acetylene are measured using a quantum cascade laser operating near 8 µm, whereas ethylene is measured with a CO2 gas laser operating near 10.6 µm. A two-color technique is used to eliminate broadband interference caused by large hydrocarbons. Measurements are compared with predictions of existing chemical kinetic mechanisms which underpredict the formation of methane and acetylene but overpredict ethylene formation.
