NEW INSIGHTS ON SULFIDATION AND OXIDIZING REGENERATION REACTIONS OF METAL OXIDES USED AS SULFUR SORBENTS

摘要

Fischer-Tropsch (FT) based XTL processes and IGCC technologies are attractive alternatives for future energy production [1,2]. In order to prevent unit corrosion or FT catalysts poisoning, deep desulfurization of syngas is achieved with metal oxides, like ZnO, which reacts according to the reaction: ZnO_((s) )+ H2S_((g)) -> ZnS_((s) )+ H2O_((g))
