Abstract
► The addition of all three calcium species to coal promoted the K2CO3-catalyzed char gasification. ► Ca(OH)2 and Ca(Ac)2 showed higher effectiveness than CaCO3. ► Calcium additive served to suppress the deactivation reaction of potassium. ► The suppression of deactivation was more pronounced for the clay-richer coals. ► Calcium and potassium also showed a mineral-unrelated synergistic effect.
