Kraft lignin biorefinery: A perspective

Bioresource Technology, 2018
Lignin is a huge energy and carbon reserve but owing to its highly biologically recalcitrant nature it is commonly regarded as a waste in lignocellulosic biomass biorefinery. To realize the lignin biorefinery, it is proposed to use Kraft lignin, isolated from black liquor from Kraft pulping mills, as starting material to be fragmented by fast pyrolysis

Fungal demethylation of Kraft lignin

Enzyme and Microbial Technology, 2015
Demethylation of industrial lignin has been for long coveted as a pathway to the production of an abundant natural substitute for fossil-oil derived phenol. In an attempt to possibly identify a novel Kraft lignin-demethylating enzyme, we surveyed a collection of fungi by using selected ion flow tube-mass spectrometry (SIFT-MS).

Desulfurization of kraft lignin

Wood Science and Technology, 2018
Kraft lignin is a product of the sulfate pulping process. It usually contains 2–3% total sulfur. Sulfur content acts as deterrent to lignin use in some areas. Sulfur-free lignins are more versatile and can be heat-treated without the release of foul-smelling sulfur compounds.

Hydrogenation of kraft lignin

Journal of Polymer Science Part C: Polymer Symposia, 1971
AbstractA series of high temperature hydrogenolyses‐hydrogenations of kraft lignin in water, organic solvents and aqueous alkali using a variety of catalysts were run. The liquefaction and distillation yields for the resulting products were measured.

Similarities in Recalcitrant Structures of Industrial Non‐Kraft and Kraft Lignin

ChemSusChem, 2020
AbstractThis work compares the structure of industrially isolated lignin samples from kraft pulping and three alternative processes: butanol organosolv, supercritical water hydrolysis, and sulfur dioxide/ethanol/water fractionation. Kraft processes are known to produce highly condensed lignin, with reduced potential for catalytic depolymerization ...
