Abstract

The products of the thermal decomposition of butane at temperatures up to 600 °C were identified by Raman spectroscopy. Heating to 500 °C resulted in the formation of a number of hydrocarbon products, in accordance with established reaction mechanisms. Heating to 600 °C, however however, led to methane as the sole product. By contrast, heating in the presence of either Al~2~O~3~ or PtAl~2~O~3~ yielded a different product distribution, attributed to interaction with Lewis acid sites on the Al~2~O~3~ surface. The Raman results were compared with data obtained by GC analysis.
