Abstract
This study proposes a model for the fast pyrolysis of biomass. A reaction scheme of a set of three parallel reactions followed by a set of two parallel reactions has been used to describe the primary and secondary reactions of biomass pyrolysis in a stationary bed reactor. A simple first-order kinetic approach has been applied to predict the product yields. The bed hydrodynamics, the mass transfer between phases and the reaction kinetics have been mathematically formulated. The effects of the operating parameters on the biomass pyrolysis product yield were simulated; the results show that the reaction temperature and nitrogen flow rate plays an important role in the yield of bio-oil. Good agreement between the predicted and measured results was obtained.
