I4EC-M«ch 1955Fine particles of Colorado oil shale were entrained in steam and retorted under controlled conditions at several temperatures over the range of 1000°to 1650°F., in order to study yield and quality of products obtained in a pilot plant.Excellent material balances were obtained, as losses ranged from 0.3 to 2.7 weight % of the material charged. Some disintegration of the shale occurred, and mineral carbonate decomposition, on a carbon dioxide basis, ranged from 3.9 weight % at 1000°to 88.8% at 1650°F. At a retorting temperature of 1000°F.
