  • 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 CO2 PRODUCED
    Publication number: 20230057765
    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 (1) is brought into contact with inert particles (2) in a thermal conversion zone (100). Thermal conversion in the absence of hydrogen, water vapour and a catalyst produces a first gaseous effluent of hydrocarbon compounds (4) and coke, which effluent is deposited on the inert particles (5). The latter is then burned in a redox chemical loop (200) in the presence of oxygen-carrying solid particles (6). The inert particles thus flow between the thermal conversion zone (100) and a reduction zone (300) of the chemical loop while the oxygen-carrying solid particles flow between the oxidation (400) and reduction zones (300) of the chemical loop.
