文摘

Kraft lignin (KL), after cleaning, revealed the highest lignin content. Harsh conditions of acetosolv and acetosolv-formosolv treatments promoted repolymerization giving high molecular weight lignins. All lignins exhibit higher content of S-type of phenols except for almond shell lignin. Olive tree pruning and almond shell lignin had the highest and most analogous amount of syringyl (S) and guiacyl (G) units.
