| Abstract: | In order to understand the carbonyl emission characteristics of methanol-diesel,a detection method for carbonyl emission was designed.Through gas capture,derivative reaction,resultant washing or extraction and HPLC analysis,formaldehyde,acetaldehyde,acrolein,propionaldehyde,acetone and similar substances were separated.The influences of detection wavelength,sampling flow rate and penetration phenomena on sampling efficiency and analysis precision were analyzed.The results show that the efficiency of absorpt... |
