“…The length range of the alkanes was from C16 to C24. Lu et al (2012) suggested that the alkanes may originally exist in the biomass as waxes rather than as products from the biomass chemical conversion. Wang et al (2011) also believed that the formation of alkanes in the oil can be mainly attributed to components (triglycerides and hydrocarbons) that are present in the extractives of biomass.…”

“…The fraction that was extracted by THF instead of n-hexane may have been the high molecule compounds, such as aromatic oligomers. Lu et al (2012) found that the intertwisting between the alkanes and some n-hexane-insoluble species in the bio-crude could make it difficult to extract the alkanes with n-hexane. In order to decrease the effect of the intertwisting and to extract as much useful substance as possible, THF was chosen as the first extraction solvent.…”

“…As a promising candidate to substitute traditional petroleum-based fuels, bio-oil derived from renewable biomass resources has stimulated extensive interests [1]. A large number of researches have been focused on producing high quality bio-oil, and one of the most attractive methods is catalytic fast pyrolysis (CFP) technology [2][3][4][5].…”

“…For example, the chromatographic techniques coupled to mass spectrometers and high-resolution mass spectrometric techniques were used extensively in the analysis of the bio-oil, biomass, and lignin samples [20][21][22][23][24]. These methods concentrate on the detection of individual species basing on the chromatographic separation and high molecular resolution.…”

Lignin is highly branched phenolic polymer and accounts 15-30% by weight of lignocellulosic biomass (LCBM). The acceptable molecular structure of lignin is composed with three main constituents linked by different linkages. However, the structure of lignin varies significantly according to the type of LCBM, and the composition of lignin strongly depends on the degradation process. Thus, the elucidation of structural features of lignin is important for the utilization of lignin in high efficient ways. Up to date, degradation of lignin with destructive methods is the main path for the analysis of molecular structure of lignin. Spectroscopic techniques can provide qualitative and quantitative information on functional groups and linkages of constituents in lignin as well as the degradation products. In this review, recent progresses on lignin degradation were presented and compared. Various spectroscopic methods, such as ultraviolet spectroscopy, Fourier-transformed infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy, for the characterization of structural and compositional features of lignin were summarized. Various NMR techniques, such as 1 H, 13 C, 19 F, and 31 P, as well as 2D NMR, were highlighted for the comprehensive investigation of lignin structure. Quantitative 13 C NMR and various 2D NMR techniques provide both qualitative and quantitative results on the detailed lignin structure and composition produced from various processes which proved to be ideal methods in practice.
