Abstract
CONTRARY to the generally held view, we have discovered that flames can be strongly catalysed, provided that the catalysts are introduced in specific flame zones. This markedly reduces the formation of carbon and of nitrogen oxides, both potential or actual air pollutants. Flame catalysis affords a rather simple and inexpensive method for their control, and the catalyst itself does not pollute the atmosphere since it is not introduced as an additive with the fuel-air stream to discharge with the flue gas, but is held in the flame.
