abstract: In this work, EmimGly ionic liquid was used for the pretreatment of bamboo biomass followed by regeneration of cellulose-rich material. Thermal degradation study of untreated bamboo and cellulose-rich material was carried out under dynamic condition using thermogravimetric analysis. Free kinetics models of Kissinger, Ozawa, Flynn�Wall�Ozawa, and Kissinger�Akahira�Sunose were used to determine the kinetic parameters of thermal degradation process. The pattern of activation energy (Ea) values with respect to % conversion values was noted different for the aforementioned models. The Ea calculated using the Kissinger method were 184 and 156 kJ mol�1, and Ozawa method were 185 and 157 kJ mol�1 of untreated and treated sample of bamboo, respectively, while the values of Ea calculated by Flynn�Wall�Ozawa and Kissinger�Akahira�Sunose were 71.7�203.4 kJ mol�1 and 281.7�230.7 kJ mol�1 for untreated and treated sample of bamboo, respectively. Calorific and CHNS values of both untreated and regenerated cellulose-rich material were measured by bomb calorimeter and elemental analyzer (CHNS), respectively. Both the calorific value and carbon content of the regenerated cellulose-rich material (15.62 J/kg, 37.86 %, respectively) were found to be less than those of untreated bamboo (17.40 J/kg and 43.14 %, respectively). The bamboo and regenerated cellulose-rich material were investigated by X-ray diffraction and X-ray Photoelectron Spectroscopy, and changes in the cellulose crystalline structure were correlated with thermal degradation behavior and kinetics parameters. © 2015, Springer-Verlag Berlin Heidelberg.
