Thermal anal. was employed as a screening technique to evaluate the activity of catalysts for the oxidn. of soot produced during combustion. Oxidn. took place over metal oxide-based catalysts at temps. much lower than in the absence of catalyst. The best results were displayed by a Cu/V/K-supported catalyst that is very active at .apprx.330. In the absence of O, 16% of the soot was oxidized by the O of the catalyst, suggesting that a redox mechanism is involved.

Abstract
Thermal anal. was employed as a screening technique to evaluate the activity of catalysts for the oxidn. of soot produced during combustion. Oxidn. took place over metal oxide-based catalysts at temps. much lower than in the absence of catalyst. The best results were displayed by a Cu/V/K-supported catalyst that is very active at .apprx.330. In the absence of O, 16% of the soot was oxidized by the O of the catalyst, suggesting that a redox mechanism is involved.File in questo prodotto:
