Abstract:

The ignition temperature and heat generation from oxidation of methane on a platinum catalyst were ; determined experimentally. A 127 micron diameter platinum coiled wire was placed crosswise in a ; quartz tube of a plug flow reactor. A source meter with a 4-wire measurement capability measured the ; resistance and current to calculate the average temperature of the surface reaction. Light-off ; temperatures varied from 730-780K for methane for a fuel-oxygen equivalence ratio of 0.3 to 1.0 at ; fuel percentages of 2-5% by volume. A model of the experimental system was created using Fluent ; coupled with Chemkin to combine an advanced chemistry solver with flow simulation. The ; experimental data was compared to the model results, which includes heat transfer and the surface ; reaction kinetics of methane on platinum. The heat transfer model obtained values close to ; experimental data for temperatures between 400K and 700K. At temperatures greater than 700K the ; model deviated with temperatures greater than the experimental results.
