Catalytic metal foils were adhered to the end wall of a shock tube with stoichiometric methane mixtures, achieving pressures from 18.9 to 24 atm and temperatures between 1178 - 1642 K. Preliminary results show little effect on volumetric ignition delay time. Emission spectroscopy, laser Schlieren, and pressure histories record before the main ignition event. Activation energies have been found, and the feasibility of this technique to study catalytic surface effects have been established.

Stoichiometric oxy-methane mixtures at pressures of 18.9 to 24 bar and temperatures between 1178 -1642 K were studied in a shock tube. Emission spectroscopy, laser Schlieren, pressure histories, and fixed wavelength laser absorption spectroscopy at 3.39 μm has been used to measure methane decomposition rates and find the absorption cross-section of methane at 3.39 μm at these conditions. Various catalytic end walls were employed to determine any surface effects caused by the catalytic material observable at a location remote from the end wall.
