乙醇的低温光催化氧化实验研究

Ethanol degradation at room temperature was investigated on a homemade batch reactor using Fourier Transform-Infrared Radiation (FTIR). It was found that FTIR could be used to track the degradation of ethanol. When ethanol molecules were degraded in the batch reactor, they were converted to CO2 via intermediates. One of the intermediates was gaseous acetaldehyde. In the batch reactor, the flux of the mixture had little effect on ethanol degradation rate. The Langmuir-Hinshelwood (L-H) kinetics could be successfully applied to describe the degradation of high concentrate ethanol. The effect of temperature on the degradation of ethanol was significant. With increasing temperature the initial reaction rate of ethanol was increased remarkably.
