Lignin from sugarcane bagasse

Values of k varied from l.lOx 10 h to 15.3x 10 h for the oxidation reaction of lignin from sugarcane straw, whereas, for oxidation reactions of lignin from sugarcane bagasse, it varied from 10.07x10 to 56.61 x 10 h . ... [Pg.659]

Activation energy calculated for the oxidation reaction of lignin from sugarcane straw was 34,239 J/mol (R =0.9676 Fig. 3), a value higher than that found in the oxidation reaction of lignin from sugarcane bagasse, which is 2,3378 J/mol (i =0.9721 Fig. 4). [Pg.660]

The first three principal components explain more than (93.14 and 91.1%) of the total variance of the system, utilizing lignin from sugarcane straw and bagasse, respectively. This means that the 390 variables for each temperature can be reduced to only three with more than 90% confidence level. Each spectrum can be reduced to a single point, as shown by PCI x PC2 and PCI x PC3 graphics (Figs. 7 and 8), where differences can be evaluated. [Pg.662]

Cellulose and lignin were obtained from sugarcane bagasse by pretreatment of the bagasse with sulfuric acid, delignification and separation of the fractions. [Pg.106]
