Resumo

thE StREaMS tO thE FCC CONVERtER UNIt ON thE CatalytIC PERFORMaNCE OF DESOx aDDItIVES.hydrotalcite-like compounds having Mg partially replaced by Cu or Mn were prepared and used as precursors for two mixed oxides (Cu-OM50 and Mn-OM50) that were evaluated for SO x removal in the presence of O 2 , NO and CO.Under SO 2 /O 2 reaction system, SO x removal was slightly higher over Cu-OM50. the addition of CO and NO to the feed markedly hindered the SO 2 oxidation over Cu-OM50 while no significant effect was observed for Mn-OM50.For the regeneration step, the use of propane instead of h 2 reduces regeneration capacity, mainly for Cu-OM50.Mn-OM50 was less affected by the feed composition, suggesting that it was a promising additive for SO x removal.
