Abstract

The thermochemical conversion of lignocellulosic biomass feedstocks offers an important potential route for the production of biofuels and value‐added green chemicals. Pyrolysis is the first phenomenon involved in all biomass thermochemical processes and it controls to a major extent the product composition. The composition of pyrolysis products can be affected markedly by the extent of softening that occurs. In spite of extensive work on biomass pyrolysis, the development of fluidity during the pyrolysis of biomass has not been quantified. This paper provides the first experimental investigation of proton mobility during biomass pyrolysis by in situ 1H NMR spectroscopy. The origin of mobility is discussed for cellulose, lignin and xylan. The effect of minerals on cellulose mobility is also investigated. Interactions between polymers in the native biomass network are revealed by in situ 1H NMR analysis.

<p>The thermochemical conversion of lignocellulosic biomass feedstocks offers an important potential route for the production of biofuels and value‐added green chemicals. Pyrolysis is the first phenomenon involved in all biomass thermochemical processes and it controls to a major extent the product composition. The composition of pyrolysis products can be affected markedly by the extent of softening that occurs. In spite of extensive work on biomass pyrolysis, the development of fluidity during the pyrolysis of biomass has not been quantified. This paper provides the first experimental investigation of proton mobility during biomass pyrolysis by in situ <hi rend="superscript">1</hi>
H NMR spectroscopy. The origin of mobility is discussed for cellulose, lignin and xylan. The effect of minerals on cellulose mobility is also investigated. Interactions between polymers in the native biomass network are revealed by in situ <hi rend="superscript">1</hi>

 An understanding of biomass pyrolysis mechanisms is of great importance for the production of biofuels and green chemicals. The pyrolysis products are highly affected by the mobility of protons. Mobility of the protons is mainly produced by the thermal conversion of lignin and xylan. Interactions between polymers in the native biomass network are evidenced.<figure type="box"><media mimeType="image" url="urn:x-wiley:18645631:media:CSSC201100442:content"></media>
