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.
Claims6
A biodigester configured to recover shale oil at ambient temperature and pressure from a feedstock, the feedstock consisting of one or more of oil shale and tar sand, the biodigester comprising:
- a rotating mixing drum with an inside surface, an outside surface, and a radial opening at a first axial end;
- a drive ring at a second axial end configured to rotate the mixing drum about an axis in both a clockwise and a counter clockwise;
- a removable lid configured to cover and rotate with the radial opening, the removable lid comprising an elastomeric gasket, wherein the elastomeric gasket is sandwiched between the radial opening and the removable lid;
- a rotating joint member attached to a center of the removable lid;
- a stationary lever arm attached to the rotating joint member, the stationary lever arm configured to hold the removable lid airtight against the radial opening;
- a hinge bar rigidly attached to the stationary lever arm and rotationally attached to a stationary frame;
- and
- a second lever arm fixedly attached to the hinge bar.
A biodigester configured to shale oil from a feedstock at ambient temperature and pressure, the feedstock including only one or more of oil shale and, tar sand, the biodigester comprising:
- a rotating mixing drum with an inside surface, an outside surface, and a radial opening at a first axial end;
- a drive ring configured to rotate the mixing drum about an axis in both a clockwise and a counter clockwise direction;
- a removable lid configured to cover and rotate with the radial opening, the removable lid comprising a elastomeric gasket, wherein the elastomeric gasket is sandwiched between the radial opening and the removable lid;
- a first lever arm attached to the removable lid, the first lever arm configured to hold the removable lid airtight against the radial opening;
- a hinge bar rigidly attached to the first lever arm and rotationally attached to a stationary frame;
- and
- a second lever arm fixedly attached to the hinge bar.
