High yield biorefinery products from sugarcane bagasse: Prebiotic xylooligosaccharides, cellulosic ethanol, cellulose nanofibrils and lignin nanoparticles

Critical Techniques for Overcoming the Diffusion Limitations in Heterogeneously Catalytic Depolymerization of Lignin

“…With the treatment by 1‐ethyl‐3‐methylimidazolium acetate, a reduced size of LS lignin subunits and released nanometer‐scale subunits of OS and K lignins with specific shape and size are observed [36] . Additionally, the topography analyses of lignin particle extracted from sugarcane bagasse by disc ultra‐refining approach reveal an irregular spherical shape and a range of 4–22 nm diameter size estimated by laser diffraction technique and AFM [38] …”

“…[36] Additionally, the topography analyses of lignin particle extracted from sugarcane bagasse by disc ultra-refining approach reveal an irregular spherical shape and a range of 4-22 nm diameter size estimated by laser diffraction technique and AFM. [38] Except for the experimental methods, the molecular dynamics simulation using a well-defined molecular force field of lignin is applied to probe into the structural properties of lignin and the detailed mechanism on model chemistry of lignin. [43] The structure and size of the simulated lignin molecules (sw6, sw10, sw16, sw20, sw30 and hw10) were investigated by Gaussian 09 software package at the level of B3LYP/6-311G (d, p).…”

Broadening the product portfolio with cellulose and lignin nanoparticles in an elephant grass biorefinery

“…For these reasons, CNFs and CNCs are useful elements to be incorporated into nanocomposites, films, foams, gels and emulsions 2 . However, only a few contributions report the production of nanocelluloses in integrated biorefinery schemes 13–16 . Since the yields of CNC and CNF production from the raw biomasses are typically low (generally 15 g of CNCs produced by acid hydrolysis from 100 g of raw substrates containing 30–40% w/w of cellulose), 17,18 coupling the production of nanocelluloses in integrated biorefineries should significantly enhance the biorefinery revenue.…”

In addition, the canonical method to produce CNCs using acid hydrolysis usually does not convert all of the biomass cellulose content, generating a residual solid fraction.…”
