| Abstract: | The activity of a series of palladium supported by FeCrAl alloy prepared by two methods after burned at different temperature was studiedThe results show that the best catalyst in study can be prepared by two method and burn ed at 900 with 220 conversion temperature and 240 total combustion temperatureIt was found that all the catalysts lose the activity after burned at 800The composition feature of catalysts surface was examed with the XRD analysis. In the catalytic experiment of normal waste gas from burning coal,the testing catalysts have excellent catalytic property with the 999% of elimination for many PAHs |
