Pyrolysis of lignin for phenols with alkaline additive
Open accessAbstract
This study is devoted to investigating the effect of alkaline additives on lignin pyrolysis for producing phenols. The effects of different types and amounts of alkaline additives, i.e., 0-20 wt.% NaOH, KOH, Na2CO3 or K2CO3, on lignin pyrolysis were tested in a fixed bed reactor. The chemicals in the pyrolysis liquid from a commercial alkali lignin with and without alkaline additive were mainly phenols including 2-methoxy-phenol, 2,6-dimethoxy-phenol, alkyl-phenols (free of methoxyl group) and 2-methoxy-4-alkyl-phenols. More vanillin and dimethoxy-benzene appeared in the pyrolysis liquid of alkali lignin and lignin purified from black liquor, respectively. While carbonate additives facilitated the production of methxoy-phenols, more alkyl-phenols were formed with the hydroxide additives. Analysis showed that all the alkaline additives promoted the reactions of decarboxylation or decarbonylation and the removal of unsaturated alkyl branch chains. The strong alkalescence of NaOH and KOH facilitated more deoxygenation of methoxyl groups so that there were more phenols free of methoxyl groups. The pyrolysis of PL resulted in the liquid yields of up to 30 wt.% (dry base), and the content of phenols was above 80% in the liquid. (C) 2014 Elsevier B.V. All rights reserved.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
