Abstract

The formation process of formaldehyde and acetaldehyde in the exhaust of spark-ignited internal combustion engines from oxidation of unburned ethanol, methane, or ethane was described. Methane and ethane were formed as intermediate products of gasoline or ethanol combustion. The oxidation reaction rate equilibrium constants for methane and ethane were determined from Gibbs function. Exhaust aldehydes were quantified for engines fueled by gasoline-ethanol blend. The results demonstrate the effect of ethanol, methane, and ethane concentration on formaldehyde and acetaldehyde formation as a function of the exhaust temperature. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
