“…The literature is abundant with fundamental studies aimed at deciphering the lignin fragmentation chemistry occurring at pyrolytic temperature regimes exceeding 200 °C (Antal 1985;Brebu and Vasile 2010;Evans et al 1986). The early work of Fenner and Lephardt examined and profiled the evolved gases from the thermal decomposition of kraft pine lignin using Fourier transform infrared analysis (Fenner and Lephardt 1981).…”

This work focused on providing a molecular understanding of the way the polymeric properties of kraft lignin and its derivatives are affected by various thermal treatments. This information was then correlated with the polymeric properties of the materials (glass transition temperature (T g ), molecular weight characteristics, and thermal stability) for a series of selectively and progressively derivatized softwood kraft lignin samples. Softwood kraft lignin was highly susceptible to thermally induced reactions that caused its molecular characteristics to be severely altered with the concomitant formation of irreversible cross-linking. However, by fully methylating the phenolic OH groups from within the structure of softwood kraft lignin, the thermal stability of these materials was dramatically enhanced and their T g reduced. While optimum thermal stability and melt re-cycling was observed with the fully methylated derivatives, fully oxypropylated phenolic substitution did not offer the same possibilities. The accumulated data is aimed at providing the foundations for a rational design of single component, lignin-based thermoplastic materials with reproducible polymeric properties when thermally processed in a number of manufacturing cycles.

“…Nevertheless, the data provide useful comparisons of reaction parameters such as temperature and heating rate. TGA of biomass samples has been extensively applied as a means of determining the characteristics of devolatilisation and also to determine kinetic parameters [39,40]. During the experimental investigation of the catalysts' surface area analysis, it was recorded that the surface of both catalysts was highly compressed.…”

“…These works, and their follow-on efforts including Broido (1976) and Bradbury, Sakai, and Shafizadeh (1979), were put to the test by Antal and Varhegyi in 1995; who, further, criticized their own (Antal) support, in-part, of these models in an earlier review (Antal, 1982). Antal and Varhegyi (1995) define cellulose pyrolysis kinetics as a mathematical description of "the pyrolytic decomposition of a small homogeneous sample of pure cellulose (free of inorganic contaminants, with a well-defined degree of polymerization and crystallinity), which is uniform in temperature throughout the course of decomposition".…”

-Decades of classical research on pyrolysis of lignocellulosic biomass has not yet produced a generalized formalism for design and prediction of reactor performance. Plagued by the limitations of experimental techniques such as thermogravimetric analysis (TGA) and extremely fast heating rates and low residence times to achieve high conversion to useful liquid products, researchers are now turning to molecular modeling to gain insights. This contribution briefly summarizes prior reviews along the historical path towards kinetic modeling of biomass pyrolysis and focusses on the more recent work on molecular modeling and the associated experimental efforts to validate model predictions. Clearly a new era of molecular-scale modelingdriven inquiry is beginning to shape the research landscape and influence the description of how cellulose and associated hemicellulose and lignin depolymerize to form the many hundreds of potential products of pyrolysis.
