The reductive catalytic fractionation (RCF) is a promising method for the development of “lignin-first” biorefineries. Apart from widely investigated virgin woody biomass, it essential to explore potential waste biomass feedstocks. Herein, RCF wheat straw examined produce lignin mono-/oligomers along with processable carbohydrate pulp. use different catalysts (Ru/C and Ru/Al2O3) catalyst loadin...

Lignin is a promising biopolymer to serve as sustainable resource for multitude of applications (e.g., thermoset materials, production bulk chemicals) thereby substituting fossil-based carbon sources. In this work, the reductive depolymerization Kraft lignin (KL) was studied in ethanol/water aided by formic acid (FA) way forward valorize lignin. The effect various process conditions elucidated ...

Ionic liquid 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BnMIm][NTf2]) can promote the generation of the ˙OOH free radical and thereby efficiently transformed the β-O-4 lignin model compound 2-phenoxyacetophenone into benzoic acid and phenol using O2 as the oxidant. Furthermore, the IL-based metal-free catalytic system can also depolymerize other lignin model compounds and ...

Kraft pulping, organosolv process and acid hydrolysis were applied on an elm clone. The solubilized lignins recovered analyzed. pulping led to with higher phenolic OH content as result of extensive cleavage ?-O-4? linkages, revealed by 13C solid state 13C?1H heteronuclear single quantum coherence nuclear magnetic resonance. This depolymerization also yielded lower molecular weight inferred size...

The need for renewable, carbon neutral, and sustainable raw materials for industry and society has become one of the most pressing issues for the 21st century. This has rekindled interest in the use of plant products as industrial raw materials for the production of liquid fuels for transportation(1) and other products such as biocomposite materials(7). Plant biomass remains one of the greatest...
