The removal of a mixture of volatileorganic compounds (CHCl3, methyl ethyl ketone,toluene and xylenes), was evaluated by adapting acommercial exhaust fan with a catalytic system applicableto small and medium enterprises. The catalystsused were Pt, Mn, Ce, Pt/Mn and Ce/Mn supportedon ceramic monoliths. It was observed thatall catalysts tested were able to reduce emissions ofvolatile organic compounds into the atmosphere. TheCO2 equivalent emission of VOCs into the atmosphere(with and without treatment) was determinedtaking into account the power consumption of theexhaust system + catalyst, being observed for all catalyststested a reduction in CO2 equivalent emissions.When a heat exchanger is attached to the exhaustsystem + catalyst to reduce power consumption, theemission of CO2 equivalent decreases appreciably inthe order of 24.8%?45.3% compared to untreatedemissions.
