Pyrolysis Of Rp-2 And Surrogate Fuels In A Jet Stirred Reactor Coupled With Synchrotron Photo Ionization Mass Spectrometry

Abstract

Combustion chemistry of real fuels are highly complicated by hundreds of individual chemical components that represent their broad composition spectrum. At the same time, typical speciation techniques are limited by the number of individual compounds which can be detected in a single experiment. In this work, the pyrolysis of RP-2 (a kerosene-based rocket fuel) was investigated in a jet stirred reactor (JSR) coupled with synchrotron photo ionization mass spectrometer (PIMS) at various temperatures (295-541 C) and photon energies (7.9-9.7 eV) at atmospheric pressure. The synchrotron PIMS is a powerful tool to identify and characterize various chemical compounds simultaneously. The mass spectrum signals were presented and the products were identified by comparing mass signal intensity versus photon energy and the corresponding standard photoionization efficiency (PIE) spectrum. The product identification showed that peaks at mass-to-charge-ratio (m/z)=54 is 1,3-butadiene (C4H6) and m/z=66 is 1,3-cyclopentadiene (C5H6). The m/z=68 indicated cyclopentene (C5H8) contribution, m/z=78 was matched with benzene (C6H6) PIE, the peak at m/z=92 confirmed toluene (C7H8), and m/z=106 was in perfect match with Xylene (C8H10). In summary, the dominant product peak is benzene followed by toluene and most peaks in the RP-2 product spectrum are aromatic compounds. The present results indicated the potential of JSR and Synchrotron-PIMS as a tool to identify multiple combustion species in a single experiment to study the kinetics of real fuels.
