Composition of Lignin-to-Liquid Solvolysis Oils from Lignin Extracted in a Semi-Continuous Organosolv Process
Løhre, Camilla; Halleraker, Hilde Vik; Barth, Tanja (Peer reviewed; Journal article, 2017-01-23)The interest and on-going research on utilisation of lignin as feedstock for production of renewable and sustainable aromatics is expanding and shows great potential. This study investigates the applicability of semi-continuously ... -
The Consistency of Yields and Chemical Composition of HTL Bio-Oils from Lignins Produced by Different Preprocessing Technologies
Halleraker, Hilde Vik; Kalogiannis, Konstantinos; Lappas, Angelos; Castro, Rafael C. A.; Roberto, Ines C.; Mussatto, Solange I.; Barth, Tanja (Journal article; Peer reviewed, 2022-06-27)This work evaluates the effect of feedstock type and composition on the conversion of lignin to liquid by solvolysis with formic acid as hydrogen donor (LtL), by analyzing the yields and molecular composition of the liquid ... -
Quantitative NMR analysis of the aqueous phase from hydrothermal liquefaction of lignin
Halleraker, Hilde Vik; Barth, Tanja (Journal article; Peer reviewed, 2020-08-06)Hydrothermal liquefaction (HTL) of biomass such as lignin could contribute to finding replacements for petroleum, both as a fuel and production of chemicals. The organic phase produced in formic acid assisted HTL of lignin ... -
Undersøking av katalysatorar ved solvolyse av lignin og analysering av produktet ved GC-MS, IR og NMR
Halleraker, Hilde Vik (Master thesis, 2011-09-08)Med tanke på at petroleum er ein avgrensa ressurs og det moderne samfunnet er så avhengig av den, er det viktig å finne alternativ. Det er nødvendig med alternativ både til drivstoff og til kjemikalieproduksjon. Solvolyse ...
