Reduction of gaseous and particulate emissions from small-scale wood combustion with a catalytic combustor

► A catalyst for reducing emissions from a batch-wise fired wood stove was studied. ► The catalyst enhanced the oxidation of carbon monoxide and organic gaseous compounds. ► Carbon monoxide, which is difficult to oxidize otherwise, was reduced during the burn out phase by nearly 80%. ► Reduction of particulate mass below particle aerodynamic size of 1 μm, including both organic matter and soot, was observed. ► Catalyst is a potential method but primary emission reduction methods should also be applied.
