IN-SITU GASIFICATION OF SOOT CONTAINED IN EXOTHERMICALLY GENERATED SYNGAS STREAM

Title:

IN-SITU GASIFICATION OF SOOT CONTAINED IN EXOTHERMICALLY GENERATED SYNGAS STREAM

Document Type and Number:

WIPO Patent Application WO2005049767

Kind Code:

A3

Abstract:

A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO₂,H₂0 and soot; and (ii) introducing the syngas and byproducts into a second reactor containing a non-carbonaceous material that traps the soot for a sufficient time such that the majority of the byproduct soot is gasified via reaction with the byproduct CO₂ and/or H₂0 to produce a syngas stream that is depleted in the soot. The system is particularly suitable for the practice of heat exchange reforming wherein a portion of the heat is recovered from the soot depleted syngas stream and used as at least a portion of the heat to facilitate the additional production of syngas via the (endothermic) catalytic reforming of natural gas and steam.
