Three new embodiments to the Chattanooga Process that convert or upgrade oil bitumen, a combination of oil sands and bitumen, a combination of sand and bitumen, and oil shale to high grade low sulfur (about 0.1 to 0.5 wt.% sulfur, or less) crude oil. The invention relates to a continuous process for producing synthetic crude oil (SCO) from oil sand bitumen which has been extracted from under ground via in situ processes, or strip mined and extracted via hot water extraction processes before upgrading. It can also apply to kerogen extracted in situ from shale underground. The process involves treating the hot bitumen with sand from an extraction process or the hot kerogen with ground shale containing kerogen in a fluid bed reactor where the reactant and fluidizing medium is only hydrogen. The invention also relates to a continuous process for producing synthetic crude oil (SCO) from oil shale kerogen. The invention relates to a continuous process for producing synthetic crude oil from ail bearing material, e.g., oil shale or oil sand (tar sand), through continuous process for producing synthetic crude oil from bituminous oil sand (tar sand) or shale. The process includes treating the oil sand (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 a feed of hydrogen provided by a feed stream having a stream containing hydrogen in a concentration greater than 90 vol % (90 vol % - 100 vol % H2).
