“…MWL also showed the strongest sp3 C-H stretching absorptions at 2932 and 2835 cm −1 among the four types of lignin, in accord with this view. This suggests that MWL might generate more hydrocarbons during pyrolysis [9]. The FTIR spectrum of EHL was similar that of MWL, but the absorption peaks were weaker from 1700 cm .…”

Pyrolysis is a promising approach that is being investigated to convert lignin into higher value products including biofuels and phenolic chemicals. In this study, fast pyrolysis of four types of lignin, including milled Amur linden wood lignin (MWL), enzymatic hydrolysis corn stover lignin (EHL), wheat straw alkali lignin (AL) and wheat straw sulfonate lignin (SL), were performed using pyrolysis gas-chromatography/mass spectrometry (Py-GC/MS). Thermogravimetric analysis (TGA) showed that the four lignins exhibited widely different thermolysis behaviors. The four lignins had similar functional groups according to the FTIR analysis. Syringyl, guaiacyl and p-hydroxyphenylpropane structural units were broken down during pyrolysis. Fast pyrolysis product distributions from the four lignins depended strongly on the lignin origin and isolation process. Phenols were the most abundant pyrolysis products from MWL, EHL and AL. However, SL produced a large number of furan compounds and sulfur compounds originating from kraft pulping. The effects of pyrolysis temperature and time on the product distributions from corn stover EHL were also studied. At 350 °C, EHL pyrolysis mainly produced acids and alcohols, while phenols became the main products at

“…To use H 2 as reactant gas, 40 ml/min helium was also purged for about 2 min to remove air and residual hydrogen before switching to reactant gas (H 2 ) with flow rate of 40 ml/ min. The actual temperature of biomass inside the quartz tube was, typically, about 50-100°C lower than that of the filament temperature [18,19].…”

“…A consideration of their origins aids the understanding of their relative abundance or absence in the pyrolysis products of the coals. The aromatic components with various hydroxyl/methoxy and alkyl substituents around the benzene rings are principally fragments derived from the lignin structures often found in wood [45][46][47]. VBC lithotypes from dark to medium to light are characterised by decreasing wood content from high to medium to low, as well as their dark to medium to light brown colour [48].…”
