Abstract
Model compound pyrolysis reaction pathways and kinetics were used in simulation of both native (e.g.. milled wood) and Kraft lignin thermolyses where either only primary or also secondary reactions are important.
Predicted products fell into one of permanent gases, tight liquids, phenolics and carbonaceous residue fractions. Product yields were more dependent on lignin type than on reaction environment.
Comparison of simulation predictions with experimental pyrolyses of actual lignins, accomplished in terms of both product identities and yields, is encouraging. It is noteworthy that the simulations are strictly a priori and incorporate no actual lignin pyrolysis information.
