Abstract
A process is provided wherein a carbonaceous material, such as oil shale, is coated with a hydrocarbon liquid, such as shale oil, prior to introduction of the carbonaceous material to a water containing, sealed system, through which the carbonaceous material is transferred to a high pressure vessel, i.e. a retort. The liquid hydrocarbon coating on the carbonaceous material effectively minimizes water absorption by the carbonaceous material in its passage through the water containing system.
