On the hydrothermal depolymerisation of kraft lignin using glycerol as a capping agent

HIGHLIGHTS

• who: MerimaHasani from the The dominating product fraction of the three fractions obtained when depolymerising softwood kraft lignin in water with glycerol is the precipitated solids (PS)The yield of this fraction decreases with residence time whereas the yield of the char fraction increases. The formation of char can therefore be minimised by keeping the residence time short. Although adding glycerol to mitigate repolymerisation was effective in the sense that the Mw of all of the product fractions were reduced, it nevertheless did not reduce the yield of char. The addition of NaOH to the reaction mixture . . .
