Stochastic Model of Lignocellulosic Material Saccharification [PDF]
, 2021 The processing of agricultural wastes towards extraction of renewable resources is recently being considered as a promising alternative to conventional biofuel production processes. Agricultural residues represent an abundant and unexploited raw material that intrinsically contains chemical energy in the form of polysaccharides.

Towards a Molecular Level Understanding of the Sulfanilamide-Soil Organic Matter-Interaction [PDF]
Science of the Total Environment 559, 347 (2016), 2016 In-depth understanding of the sorption mechanisms of organic pollutants, like the antibiotic sulfanilamide (SAA), in soil requires a combined experimental and theoretical approach. Therefore, sorption experiments of SAA on well-characterized samples of soil size-fractions were combined with the modeling of SAA-soil-interaction via quantum chemical ...

ISOLASI DAN PENCIRIAN LIGNIN DARI LINDI HITAM DAN SENGON UNTUK BAHAN PEREKAT
Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017 Lignin is the polymer which has been degraded and removed in pulping processes. The occurance of lignin as a waste product in pulp mills has made it an attractive raw material for adhesives eversince the ...

Journal of the agricultural chemical society of Japan, 1956 Coniferyl alcohol, 1-(4-hydroxy-3-methoxyphenyl)-propanediol-(1,3) and 1-(4-hydroxy-3-methoxyphenyl)-propanediol-(1,2) have been found to react with hydrogen sulfide. From the results of paper chromatography and U.V. spectra a portion of the sulfidation products obtained from the first and second compounds appear to be identical. Upon alkali treatment,

Development of an aqueous lignin mixture thermophysical model for hydrothermal liquefaction applications using uncertainty quantification tools [PDF]
arXiv, 2022 A thermophysical model is developed that can predict the properties of two lignin mixtures, black liquor and lignosulfonates, up to 50% mass fractions, at hydrothermal conditions. An uncertainty quantification framework linked with classic thermodynamical modelling was included to account for the extreme variability of the raw material.
