The invention relates to a continuous process for producing synthetic crude oil from oil bearing material, e.g., oil shale or tar sand, through continuous process for producing synthetic crude oil from bituminous tar sand or shale. The process includes treating the tar sand or shale to produce a fluidizable feed, feeding the fluidizable feed to a fluidized bed reactor, and fluidizing and reacting the fluidizable feed in the fluidized bed reactor with substantially only hydrogen.

Process and apparatus for converting oil shale or tar sands to oil

The invention relates to a continuous process for producing synthetic crude oil from oil bearing material, e.g., oil shale or tar sand, through continuous feeding and calcining, hydrocracking and hydrogenating kerogen or bitumen.

The invention relates to a continuous process for producing synthetic crude oil from oil bearing material, e.g., oil shale or tar sand, through continuous loading, calcining and unloading operations in three triangularly placed reactor tubes that are loaded with oil bearing material from a common feed source.
