Abstract

The feasibility of high pressure pyrolysis experiment in a rapid compression machine is tested by using ethanol as a reactant. A premixed homogeneous ethanol-nitrogen-argon mixture is prepared and compressed to reach 880 K and 20 bar condition and the mixture undergoes pyrolysis, which is validated by direct sampling of the compressed mixture and conducting speciation through a gas chromatography. Over 10 species are detected and an up-to-date ethanol kinetic model is applied to gain insight into the formation of these intermediate species, which reveals some, but not all, pyrolysis pathways. Results suggest that further studies on the ethanol kinetics are necessary regarding the findings from this study, for example pyrolysis experiments with a non-diluted reactant could propose some reaction pathways accompanying exothermicity.
