Catalytic combustion of methane has been studied in the presence of catalysts supported on ceramic foams. Low concentrations of NO
x
(in the range of 5 - 50 mg m
-3
) were observed with all catalysts used. Concentrations of CO depended strongly on the type of the catalyst, its composition, methane throughputs and varied from 4 400 to 0 mg m
-3
. Minimum CO concentration (0 - 8 mg m
-3
) was gained with 0.04% Pt on ceramic foam modified with both alumina Al
