Abstract

Smoke forming particles entrained in a gas stream containing oxygen is passed through a catalyst unit in which a supported catalytic material is disposed to inhibit straight through flow of the said particles so that, firstly, the probability of contact between the particles and the catalytic material is increased and, secondly, turbulence is imparted to the gas stream to increase the probability of contact between the particles and the catalytic material. The support may be randomly arranged ceramic pellets, interwoven or randomly oriented wire as mesh or perforated corrugated sheet or foil which has been stretched. [GB2024646A]
