Abstract

A mathematical model is presented which describes mass and energy transport during rapid pyrolysis of fibrous cellulose particles. Radiative heat transfer within porous cellulose is modeled by using the method of zones. Solution of the governing equations shows that both mass- and heat-transfer resistances influence product composition from pyrolysis even for cellulose particles as small as 0.5 mm in diameter. Heating rate has little influence on product composition, but increasing the total pressure results in a decreased condensible product yield. Radiative heat transfer plays a minor role within the solid for the conditions simulated. The model is useful for identifying critical parameters and conditions in pyrolysis and for predicting trends in product yields.
