| abstract |
The subject matter herein provides a biotic method for recovering one or more hydrocarbons from a feedstock that includes one or more of oil shale, bituminous tar sand, coal and cellulous at atmospheric temperature and pressure. The method comprises loading the feedstock into a container, treating the feedstock in the container with a biomedium of micro-organisms, and forming an essentially liquid mixture from the feedstock and the biomass by rotary tumbling the feedstock and the biomedium in the container. The essentially liquid mixture is then separated into the one or more hydrocarbons by centrifuging. |
