FUEL, OIL AND HIGH TEMPERATURE EFFECTS ON NOBLE METAL OXIDATION CATALYSTS

Ageing tests were conducted on two monolithic noble-mental oxidation catalysts on an engine using various fuels and oils, and in a furnace with an air atmosphere. The activity of the aged catalysts was determined by laboratory apparatus and related to the results of chemical analyses of the catalyst specimens. It was found that pure thermal ageing at temperatures above 700 degrees C can lead to a severe loss of activity even without additional catalyst poisoning. Of the impurities contained in the fuel, phosphorus is the most dangerous catalyst poison.
