Liquefaction of Kraft Lignin at Atmospheric Pressure
(Tech Science Press, 2019)
[EN]Kraft lignin was liquefied using polyethylene glycol #400 (PEG) and
glycerol (G) in a weight ratio of 80/20 (w/w) and sulphuric acid (SA) as catalyst
under atmospheric pressure at 160ºC. The three independent variables: ...
Liquefaction of Kraft lignin using polyhydric alcohols and organic acids as catalysts for sustainable polyols production
(Elsevier, 2019)
[EN]In this work, three different organic acid catalysts, (acetic acid, lactic acid and citric acid), are proposed as an
alternative to common catalysts used in the liquefaction process of Kraft lignin. These organic acids ...
