Descrizione generale

Lignin, alkali is a complex, three dimensional polymer that is also known as kraft lignin that has undergone hydrolytic degradation. It is one of the major components of lignocellulosic materials. Lignin is a major product for second generation bioethanol production and is an impurity in the separation of cellulose from wood.

Applicazioni

Lignin, alkali can be used as a surface treatment agent for composites of natural fibers with petroleum based resins. It can be used as a biosorbent for potential applications in removing toxic metal ions from wastewater.

Over the long term, soil carbon (C) storage is partly determined by decomposition rate of carbon that is slow to decompose (i.e., recalcitrant C). According to thermodynamic theory, decomposition rates of recalcitrant C might differ from those of non-recalcitrant C

Maximizing the production of aromatic hydrocarbons from lignin conversion by coupling methane activation without solvent was investigated over Zn-Ga modified zeolite catalyst. The co-loading of Zn and Ga greatly improves lignin conversion, arene yield along with BTEX (i.e., benzene, toluene

Bacterial protein secretion represents a significant challenge in biotechnology, which is essential for the cost-effective production of therapeutics, enzymes, and other functional proteins. Here, it is demonstrated that proteomics-guided engineering of transcription, translation, secretion, and folding of ligninolytic laccase balances

Copolymerization of N-isopropylacrylamide (NIPAM) with technical hardwood kraft lignin (HWKL) was achieved by atom transfer radical polymerization (ATRP) using a selectively modified lignin-based macroinitiator. The degree of polymerization (DP) of polyNIPAM graft side chains was affected by varying the ratio

We have found that 1-alkyl-3-methylimidazolium chloride ionic liquids (ILs) can form immiscible liquid mixtures with some polyethylene glycols (PEGs). Binary mixtures of 1-ethyl-3-methylimidazolium chloride with PEG of molecular weight 1500, 2000, or 3400 g mol(-1), or of 1-butyl-3-methylimidazolium chloride with
