A comparison is made with non-hydrotalcite mixed oxide supports as well as pure alumina. The most promising material NaMnO x /Al2O3 was wash-coated on a cordierite core and its SO x trap capacity was compared with the performance of the powder and the slurry. The slurry as well as the monolith-supported material showed an SO2 uptake of 93% over 7h time-on-stream corresponding to 20wt.% sulphate. DRIFT spectroscopy revealed the prevailing sulphate formation on Mn-related sites and Na. Regeneration of the trap with CO/H2 (λ=0.99) at 600°C was not completely possible.
