The modeling of large scale chemical reactors requires knowledge
of the reaction rates, either on a global or intrinsic level
depending on the complexity of the reactions, as well as the mass
and heat transfer rates. In this review, published reaction rate
models and proposed mechanisms for the pyrolysis of woody
biomass were compared. There are more than one hundred
components involved in the pyrolysis of sawmill residues and
therefore the approach has been to develop “lumped” models
where either feedstock and/or products are grouped. Experimental
data generated in our lab was compared with various models and
the CPD model was sufficient for bio-oil and bio-char yields. Also,
the competitive model proposed by Chan et al. predicted the biooil
product most accurately
