A study on supercritical water gasification of black liquor conducted in stainless steel and nickel-chromium-molybdenum reactors

摘要

BACKGROUND: This study presents supercritical water gasification (SCWG) as an alternative treatment process for black liquor: investigating the impacts of black liquor constituents, temperature and catalyst. The preliminary experiments include SCWG of sucrose and isoeugenol in stainless steel reactor, as model compounds of sugars and lignin. Then, the experiments of SCWG of black liquor are performed in stainless steel and INCONEL 625 reactors.
