Abstract
A process for producing a fuel gas and sulfur from a hydrocarbon fuel wherein a fuel oil containing sulfur is at least partially combusted in a fluidized bed of sorbent material which produces a substantially sulfur free fuel gas and a sulfided sorbent. The sulfided sorbent is passed to a second fluidized bed which regenerates the sulfided sorbent and produces a sulfur dioxide containing gas. The latter gas is contacted with granular coal in the presence of steam to reduce the sulfur dioxide to elemental sulfur.
