Abstract
Hot, non-oxygenous gas at carefully controlled quantities and at predetermined depths in a bed of lump oil shale provides pyrolysis of the contained kerogen of the oil shale, and cool non-oxygenous gas is passed up through the bed to conserve the heat inventory for a viable process. The bed being fed at the top with raw shale and retorted shale being removed at the bottom provides a constant depth, continuously moving bed of shale, for a continuous process.
