In the partial oxidation of acetone, an acetone conversion greater than 70 % and an oxygen conversion greater than 90 % are reached in the smaller crystallite size sample at 350 °C, whereas only less than 5 % of oxygen are converted in the larger crystallite size sample. At 400 °C, acetone and oxygen conversion as well as absolute carbon monoxide and hydrogen conversion in the latter sample surpass the values of the smaller crystallite size sample, as there is a decrease in acetone conversion, but not in oxygen conversion. Carbon monoxide and hydrogen are more abundant than carbon dioxide in both samples as products. In the setting of steam reforming of acetone with co-dosing of oxygen equal to the concentration of acetone, oxygen conversion is much higher than suggested by the current acetone conversion or product evolution up to a temperature of 200 °C. Acetone conversion remains below 15 % up to the maximum temperature, while more than 90 % of oxygen is consumed at 400 °C in both samples. As carbon dioxide is the most abundant product, it is suggested, that a relatively high amount of oxygen is required to form high oxidation state carbon species on the catalysts surface before carbon dioxide is evolved. When co-dosing water to the partial oxidation of acetone experiment, carbon dioxide seems to be preferred as a product to carbon monoxide and hydrogen. This can be explained by the slightly oxidising character of water, but might also be related to a different ratio of acetone to oxygen or the much higher absolute concentration of the reagents in the partial oxidation of acetone experiment without water.
