Abstract
A process for photochemically treating hydrocarbons and halogenated or partially oxidized hydrocarbons in a gaseous or vaporous mixture, by exposing the mixture to ultraviolet light, preferably of relatively short wavelength in the presence of oxygen or its allotropes, in order to oxidize the hydrocarbons to very simple compounds.
Claims13
A process for photochemically treating a gaseous or vaporous stream containing an oxidizable contaminant, said process comprising exposing said contaminant to ultraviolet radiation from a source of radiation emitting ultraviolet wavelengths shorter than 2100 A in the presence of ozone thereby oxidizing said contaminant to form simple, gaseous products, said ozone being in addition to any ozone formed by said source of ultraviolet radiation.
