Origin of Organic Pollutants from the Combustion of Alternative Fuels: Phase IV Report

The research described in this report resulted from laboratory experiments of the conversion of neat methanol and ethanol over a Pd/Pt catalyst. These experiments resulted in a number of partially oxidized reaction products that have not been reported in engine tests, or in higher temperature, post-combustion, lab-scale, gas-phase oxidation studies. These compounds have relatively lowreactivities, so their impact on tropospheric smog formation may be fairly minimal. However, the health effect impacts of these compounds may be a significant issuse. Further study is needed on these components and their effect on human health.
