Claim Text:
1. A method for the co-production of a sulfur-containing raw synthetic gas and an essentially desulfurized carbon-containing solid residue from a sulfur-containing heavy petroleum residue feedstock selected from the group consisting of petcoke, an asphaltenic-rich residue, and combinations thereof, the method consisting essentially of: (a) feeding a particulate sulfur-containing heavy petroleum residue feedstock into a bubbling fluidized-bed reactor with a residence time of less about 4 minutes or less; (b) converting said sulfur-containing heavy petroleum residue feedstock to a sulfur-containing raw synthetic gas by partial oxidation reaction of said feedstock, the partial oxidation reaction taking place in the bubbling fluidized-bed gasification reactor in the presence of water and a partial oxidation agent at a temperature of 1000° C. or less and a pressure of about 10 atm or less, thereby also producing an essentially desulfurized carbon-containing solid residue that contains between about 47% wt to about 55% wt of an initial amount of carbon in the feedstock; and (c) separately recovering the essentially desulfurized carbon-containing solid residue and the sulfur-containing raw synthetic gas, wherein all reactions involved in the co-production method, including consumption of O
