Catalytic conversion network for lignocellulosic biomass valorization: a panoramic view

Abstract

Efficient utilization of lignocellulosic biomass to substitute fossil resources is an effective way to promote the sustainable development of current society. Numerous lignocellulose valorization routes for the production of value-added...

Chemocatalytic production of sorbitol from cellulose via sustainable chemistry – a tutorial review

“…Cellulose can be depolymerized into glucose as shown by numerous research efforts that focus on upgrading cellulose into platform molecules such as 5-hydroxymethylfurfural, ethylene glycol, gluconic acid and sorbitol, in which the production of furfural and 5-hydroxymethylfurfural via glucose dehydration destroys the sugarsteric structure, whereas its conversion to hexitols can maintain some of the original steric structure without C-C bond dissociation. 13,14 Hence, the hydrogenation of glucose to sorbi-tol has an important position in future biorefineries for industrial production of chemicals.…”

MFI zeolite with confined adjustable synergistic Cu sites for the hydrogenation of levulinic acid

“…The utilization of cellulosic biomass meets the global interest in renewable and green chemistry against the rapidly increasing consumption of fossil resources and consequent environmental problems. 4 Among these, levulinic acid (LA) is one of the most important biomass platform molecules that can be easily and economically produced from cellulosic feedstocks by conventional hydrolysis. 5 LA can be further converted to various high-value-added chemicals, especially γ-valerolactone (GVL).…”

Insight into the Keratin Ratio Effect of the Keratin/Cellulose Composite Fiber

“…The desire for new solvents that can improve the efficiency of keratin dissolution and extraction has attracted the attention of scientific researchers. As we all know, ionic liquids (ILs) are a kind of effective solvents, and, in particular, their strong hydrogen-bonding ability can be used to easily disrupt the hydrogen bond network formed between the hydroxyl groups and the oxygen of the adjacent ring within the cellulose molecules and then dissolve the cellulose. − In addition, ILs also show their ability to dissolve keratin at the desired temperature and a certain amount of time . ILs have been used to prepare keratin–cellulose composites.…”
