Abstract
The hydrogen sulfide concentration of a gas of relatively higher hydrogen sulfide concentration is reduced by introducing the gas to a fragmented permeable mass of oil shale for contacting the oil shale in the substantial absence of free oxygen. This yields a gas with relatively lower hydrogen sulfide concentration which is withdrawn from the fragmented permeable mass of oil shale.
