This paper presents a detailed review of experimental and modeling work carried out on devolatilization of different kinds of wood under fluidized bed combustion/pyrolysis conditions. Laboratory scale experimental studies as well as analytical, phenomenological and numerical modeling works have been reviewed and presented. It has been found that attempts to determine the kinetics in actual fluidized bed conditions have been carried out. There is no single devolatilization model that incorporates all the physical and chemical phenomena occurring during devolatilization. Moreover, the physical phenomenon of primary fragmentation has not been adequately incorporated in the models. Also, non-intrusive temperature measurement techniques need to be developed and demonstrated.
Author Keywords: Wood, Devolatilization, Experiments, Modelling, Review.

Abstract
This paper presents a detailed review of experimental and modeling work carried out on devolatilization of different kinds of wood under fluidized bed combustion/pyrolysis conditions. Laboratory scale experimental studies as well as analytical, phenomenological and numerical modeling works have been reviewed and presented. It has been found that attempts to determine the kinetics in actual fluidized bed conditions have been carried out. There is no single devolatilization model that incorporates all the physical and chemical phenomena occurring during devolatilization. Moreover, the physical phenomenon of primary fragmentation has not been adequately incorporated in the models. Also, non-intrusive temperature measurement techniques need to be developed and demonstrated.
