METHOD FOR LOW-SEVERITY GASIFICATION OF HEAVY PETROLEUM RESIDUES.

摘要

A method for co-producing a sulfur-containing raw synthetic gas and an es sentially desulfurized solid residue from a sulfur-containing heavy petroleu m residue feedstock, comprising feeding a bubbling fluidized-bed gasificatio n reactor with the feedstock, and converting the feedstock to a raw syntheti c gas by a partial oxidation reaction in the presence of water at a temperat ure at or below about 1000oC and a pressure at or below about 10 atm, thereb y also producing an essentially desulfurized solid residue, while the sulfur components are essentially comprised in the raw synthetic gas; and separate ly recovering the essentially desulfurized solid residue and the sulfur-cont aining raw synthetic gas.
