Abstract: A method for co-producing a sulfur-containing raw synthetic gas and an essentially desulfurized solid residue from a sulfur-containing heavy petroleum residue feedstock, comprising feeding a bubbling fluidized-bed gasification reactor with the feedstock, and converting the feedstock to a raw synthetic gas by a partial oxidation reaction in the presence of water at a temperature at or below about 1000° C. and a pressure at or below about 10 atm, thereby also producing an essentially desulfurized solid residue, while the sulfur components are essentially comprised in the raw synthetic gas; and separately recovering the essentially desulfurized solid residue and the sulfur-containing raw synthetic gas.
