A novel modification of Klason lignin quantitative method In this paper, a convenient method has been reformed which enables a quick, lightly labored and accurate analysis of acid-insoluble lignin (or Klason lignin ; abreviated to KL) in both woods and non-wood. The method in essentially based...
Cleavage and hydrodeoxygenation (HDO) of C-O bonds relevant to lignin conversion using Pd/Zn synergistic catalysist[M].Chemical science 2013,2(2).Parsell, T. H.; Owen, B. C.; Klein, I.; Jarrell, T. M.; Marcum, C. L.; Haupert, L. J.; Amundson, L. M.; Kenttamaa, H. I....
2B), the Ti−ligand peak of CF/TiO2-3 in the first shell positively shifted with the comparison of the standard anatase TiO2, attributing to the Ti−O/N bonds. The quantitative parameters of Ti−O/N bonds were further obtained by fitting EXAFS curves (Fig. 2C and D) and the ...
Phenols in the rice husk extract:The presence of phenolic compounds was indicated by their corresponding peaks, as illustrated inTable 1. Phenolic compounds originated by the degradation of rice husk [35] that contained a large amount of lignin [36]. Phenyl propane group present in lignin is th...
Hydrogen as an environmentally friendly fuel can be produced by photocatalytic procedures from aqueous systems, utilizing H2S, an industrial side-product, by conversion and storage of renewable solar energy. Although composites of CdS and ZnS prepared by
In the present work, we investigated the first route, and Pd was coupled with two different non-noble transition metals, Ni and Zn. The goal was to find suitable, high performance and cheaper catalysts able to guarantee a good catalytic activity and stability toward the hydrogenation of MA to...
