The article reports on the "liquid wood" bioplastic that was created by German scientists at the Fraunhofer Institute and the spin-out company TECNARO using lignin waste from paper production. The bioplastic so high quality it can be used to make toys. The researchers mixed the bioplastic with ...
In this work, the ionic liquid, 1-ethyl-3-methylimidazolium acetate ([Emim][CH3COO]), was used as a pretreatment solvent to extract lignin from wood flour. The cellulose in the pretreated wood flour becomes far less crystalline without undergoing solubilization. When 40% of the lignin was ...
Comparative Study of Solid-Phase Extraction and LiquidLiquid Extraction for the Reliable Quantification of High Value Added Compounds from Oxidation Processes of Wood-Derived Lignin Technologies and processes for lignocellulosic conversion in biorefineries are emergent subjects of research for which a reliable...
In this study, gas chromatographycoupled with quadrupole time-of-flight mass spectrometry (GC/Q-TOFMS), combined with post-target and nontarget analysis methods, wasused to analyze the liquid phase products generated from lignocellulosicbiomass liquefaction, such as poplar wood, pine wood, cellulose...

The catalytic cracking of wood-derived fast pyrolysis bio-oils has been tested at 360 °C over various zeolites like HZSM-5, SAPO-11, SAPO-6 and MgAPO-36 [222–225]. In all these cases, coke formation on the catalyst and char deposition in the reactor were representing in mass about ...
In addition, lignin in compression wood has large proportion of p-hydroxyphenyl propane units27. From these properties, compression wood is generally difficult to use for industrial processing28. However, softwood especially juvenile wood is estimated to contain non-negligible amounts of compression ...
