The objective of this project was to determine the impact of alternative fuels on air quality, particularly ozone formation. The alternative fuels of interest are methanol, ethanol, liquefied petroleum gas, and natural gas. During the first year of study, researchers obtained qualitative data on the thermal degradation products from the fuel-lean (oxidative), stoichiometric, and fuel-rich (pyrolytic) decomposition of methanol and ethanol. The thermal degradation of ethanol produced a substantially larger number of intermediate organic by-products than the similar thermal degradation of methanol, and the organic intermediate by-products lacked stability. Also, a qualitative comparison of the UDRI flow reactor data with previous engine test showed that, for methanol, formaldehyde and acetone were the organic by-products observed in both types of tests; for ethanol, only very limited data were located.
