PILOT-PLANT PHOTOMINERALIZATION OF VOLATILE ORGANIC-COMPOUNDS IN AIR,BY PHOTOCATALYTIC MEMBRANES IMMOBILISING TITANIUM-DIOXIDE AND PROMOTING PHOTOCATALYSTS

Photomineralization of some volatile organics in air, as model compoun ds, (methanol, ethanol, acetone, methyl-i-butyl-ketone, ethyl acetate, formic acid, acetic acid, dichloromethane, trichloroethene, and tetra chloroethene) has been studied at 315+/-4 K, by a pilot plant consisti ng in a PHOTOPERM(R) WW membrane module, employing photocatalytic memb ranes, immobilising 30+/-3 wt.% TiO2 and 6 wt.% each of two Co(III) an d V(V) organometallic compounds, as promoting photocatalysts. Times co rresponding to 95% mineralization were monitored by analysis of CO2 pr oduction.
