Abstract:
1. A process for refining raw materials containing at least one of oil and bitumen, the process comprising: supplying the raw materials to a fluidized bed reactor; volatilizing the raw materials to generate fuel gas in the reactor at a reactor temperature of from 300 to 1000° C. and at a reactor pressure of from 0.001 to 1 bar; obtaining at least one gas stream containing light hydrocarbons from the reactor and recycling the at least one gas stream to the reactor as a fluidizing gas; introducing solids remaining in the reactor, including non-evaporated fractions of heavy hydrocarbons, into a furnace; performing a staged combustion of the non-evaporated fractions of heavy hydrocarbons in a substoichiometric stage and in a superstoichiometric stage in the furnace at a furnace temperature of from 600 to 1500° C. so as to obtain hot solids in the furnace; recirculating the hot solids from the furnace into the reactor; and separating, by a sealing device, an oxidizing atmosphere of the furnace from an atmosphere of the reactor.
