An experimental study of isobutane oxidation at transition temperatures
01 Jan 1986
Abstract
The oxidation of isobutane at temperatures in the range 563-693 K has been studied experimentally using a static reactor. Gas chromatographic analysis was used to measure stable species concentrations. The experimental results were used to postulate the main reaction paths of the mechanism at these temperatures. A region of negative temperature coefficient (NTC) was observed between 650 and 680 K. Changes in the product yields and product distribution indicated a transition in the mechanism across the NTC region, from low to intermediate temperatures. Analysis of the experimental results and comparison with results for other fuels, such as n-butane, propane and propene, indicated that the NTC and mechanism transition were strongly dependent on the shift in the equilibrium of CH/sub 3/ + O/sub 2/ <==> CH/sub 3/O/sub 2/. The results are also discussed in relation in relation to recent engine results.
