摘要：

An ethanol oxidation test bench, which is mainly composed of a flow reactor, was designed and built. A stainless steel pipe was installed into a gasoline engine exhaust pipe, through which the sample gas flows into the reactor with the typical exhaust temperature environment. Ethanol oxidation characteristics were investigated in the flow reactor under the real exhaust temperature environment. The experimental results show that the ethanol initial oxidation temperature and aldehydes characteristics are obtained by ethanol oxidation in the flow reactor. Then, the effects of exhaust gas temperature and flow rate on ethanol oxidation, aldehydes formation and oxidation were investigated. It is found that ethanol mass fraction decreases with the increase of the temperature.However, aldehydes increase at first and then decrease with the increase of temperature. In addition, the critical temperature of the formation and oxidation of aldehydes is fitted from experiment data. The highest acetaldehyde mass fraction is found to be about 15 times higher than the formaldehyde mass fraction at the critical temperature. © 2017, Editorial Office of the Transaction of CSICE.
