This patent describes a system for removing sulfur species from a stream of fuel gas produced by the gasification of sulfur-containing fuel. It comprises a vertically oriented housing, a bed of particulate sulfur sorbent, means for directing a stream of sulfur-bearing fuel gas upwardly through the bed in the housing, vertically oriented first conduit means contacting an upper region of the bed, second conduit means in communication with the vertically oriented first conduit means at a location underlying the bed, means for introducing a steam of oxygen-containing gases into the second conduit means, separating means coupled to the second conduit means at the preselected location and third conduit means in communication with the separating means and a lower region in the bed for conveying the separated regenerated sorbent from the separating means into the lower region of the bed.
