Integrated method for thermal conversion and indirect combustion of a heavy hydrocarbon feedstock in a redox chemical loop for producing hydrocarbon streams and capturing the coproduced

Abstract

The invention relates to an integrated method for thermal conversion and indirect combustion of a heavy hydrocarbon feedstock in a redox chemical loop for producing hydrocarbon streams. The heavy hydrocarbon feedstock () is brought into contact with inert particles () in a thermal conversion zone (). Thermal conversion in the absence of hydrogen, water vapour and a catalyst produces a first gaseous effluent of hydrocarbon compounds () and coke, which effluent is deposited on the inert particles (). The latter is then burned in a redox chemical loop () in the presence of oxygen-carrying solid particles (). The inert particles thus flow between the thermal conversion zone () and a reduction zone () of the chemical loop while the oxygen-carrying solid particles flow between the oxidation () and reduction zones () of the chemical loop.
