Abstract

original image

Thermochemical conversion of biomass starts with its pyrolysis. The intrinsic kinetics and heats of reactions for the three first reactions in cellulose pyrolysis are measured. The products from pyrolysis of cellulose can vary depending on the temperature of pyrolysis, with levoglucosan being formed at higher temperature. Furthermore, pyrolysis can be either exothermic or endothermic depending on the products formed.
