Mixed solld solutions magnesium-alumina spinel catalyst, MgAl_2O_4·xAl_2O_3·yM (01, the activity decreases which was due to M and spinel coexist in the catalyst. The results of reduction-oxidation (red-ox) cycle tests showed that introducing rare earth cerium to spinel could improve the de-SO_x activity. Of all the catalysts, 0.1 Ce/MgAl_2O_4·M is promising catalyst which has the highest activity. 30% propane as reducing gas is superior to 30% H_2.
