Embodiment Construction

[0030] overview

[0031] Particular embodiments of the invention relate to apparatus and methods for heating hydrocarbonaceous material (e.g., tar sands or hydrocarbonaceous rocks, such as coal or oil shale blocks) within an enclosure (e.g., a mine or reservoir or vessel) method. Hydrocarbon-bearing rock is directed into the enclosure to form a rock bed (eg, a packed bed) therein. Oxygen can be evacuated (eg, under vacuum or through) to create a substantially anoxic environment within the enclosure. In various embodiments, the enclosure may be a mine shaft, or a reservoir or container. The enclosure may be completely or partly below ground level and partly or completely above ground level.

[0032] Operation of the heater in thermal communication with the hydrocarbon-bearing rock may heat the rock sufficiently to convert the kerogen or bitumen into pyrolysis formation fluids, including hydrocarbon pyrolysis fluids. Formation fluids may be recovered through production tubin...

Abstract

Hydrocarbon-bearing rock (eg, mined oil shale) is directed into an excavated enclosure (eg, a mine shaft or reservoir) to form a rock bed there. One or more heaters, such as molten salt heaters, are operated to pyrolyze the kerogen or bitumen of the rock. One or more heaters (eg, molten salt heaters) are operated to pyrolyze the kerogen or bitumen of the rock. In some embodiments, a hydrocarbon reflux cycle is maintained within the enclosure to convectively heat the hydrocarbon-bearing rock by boiling hydrocarbon fluid from a reservoir at the bottom of the enclosure such that steam penetrates The top of the enclosure, congeals, and falls back into the bedrock. Alternatively or additionally, the rock may be heated by heaters embedded in the walls and / or floor of the enclosure. Some embodiments relate to methods for upgrading mined coal to recover hydrocarbon pyrolysis fluids and upgraded coal (eg, anthracite).

Description

technical field [0001] Embodiments of the invention relate to methods and apparatus for heating kerogen or bituminous rock beds, for example, to produce pyrolysis fluids therefrom. Background technique [0002] Hydrocarbons obtained from subterranean formations are commonly used as energy sources, feedstocks, and as consumer products. Concerns about the depletion of available hydrocarbon resources, as well as concerns about the overall decline in the quality of produced hydrocarbons, have led to the development of more convenient methods of recovery, disposal, and / or utilization of available hydrocarbon resources. In situ processing methods can be used to remove hydrocarbons from subterranean formations that were previously difficult to obtain and / or expensive to extract using existing methods. The chemical and / or physical properties of the hydrocarbon species in the subterranean formation need to be altered so that the hydrocarbon species can be more easily removed from th...
