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.

An ebullated bed process for the hydroconversion of heavy hydrocarbon feedstocks that provides for high conversion of the heavy hydrocarbon with a low sediment yield. The process uses for its catalyst bed small particles of a specifically defined shaped hydroprocessing catalyst which is contacted with the heavy hydrocarbon feedstock under hydroconversion conditions and yields a hydrocarbon conversion having a relatively low sediment content.

An improved method of operating a conventional ebullated bed process for the hydroconversion of heavy hydrocarbon feedstocks so as to provide for low or reduced sediment content in the conversion product without the loss of hydrodesulfurization function.
