Abstract:
Biomass feedstocks having altered lignin concentration and/or lignin chemical composition could be attractive with respect to improving the yield of valuable chemicals in fast pyrolysis. pyGCMS was used to to investigate the correlation between conversion products and biomass, being low HCT poplar mutants (Populus nigra), which are characterised by lignin having an abnormally high Hunit content. Regarding the production of phenolic compounds, increases in nonmethoxylated phenols were observed, at the expense of monomethoxylated phenols. Catalytic fast pyrolysis with zeolite Y was also performed on the mutant and wild type poplar samples. Although the use of the catalyst failed to increase the production of phenols, differences in the phenolic spectrum of the fast pyrolysis vapours indicated differences in the thermal decomposition behaviour of the Hrich lignin in the low HCT mutant versus wild type poplar.
