Lignin separation and fractionation by ultrafiltration
Abstract
Abstract Membrane technology allows the separation from the black liquor of different lignin fractions with a specific molecular weight being able to be used in the synthesis of several high value-added products (chemical reactants, resins and biocomposites, antioxidant agents, etc.). In the present study, black liquor resulting from the alkaline pulping of the Miscanthus sinensis (7.5% NaOH, 90 min and 90 °C) has been subjected to several stages of ultrafiltration, by using ceramics membranes of different cut-offs (5, 10 and 15 kDa). The different permeates obtained have been characterized (density, % TDS, inorganic and organic content and lignin recovery in each fraction), analyzing the effectiveness of the conditions of the pulping and ultrafiltration processes. Subsequently, the lignins have been isolated by acid precipitation and studied by means of different analytical techniques, being able to establish the differences in their chemical structure and thermal behaviour, and subsequently their more adequate commercial application.

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.
