Abstract
SO x traps were prepared using hydrotalcite materials of different composition and their SO x storage properties were monitored during temperature cycling (50–600 °C) under continuous feed streams (50 ppm SO2, 6 vol.% O2, 5 vol.% CO2, 100 ppm NO) at a space velocity of 144,000 L/(kg h). 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 7 h time-on-stream corresponding to 20 wt.% 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.
