摘要
A process and apparatus for direct coking of tar sands which includes contacting the tar sand with heat transfer particles resulting from combustion of coked sand effluent from the coking process, and transporting the combination up a riser/mixer to a coking vessel whereby separation of oil and hydrocarbon gases from the sand is initiated. The tar sand is introduced into a fluid coking vessel which has at least two coking zones. The first coking zone is substantially at the top of the vessel whereas the second coking zone is immediately below the first coking zone and includes a stream of hot spent sand so that a more severe coking temperature is present in the second coking zone. A product stream of oil and light hydrocarbon gases, recovered from the riser/mixer and coking process, is directed to a separator located above said coking vessel in which the heavy oil is removed and preferably directed to the second coking zone.
