| Abstract | Abstract In order to obtain the effect of torrefaction pretreatment on chemical structure and pyrolysis reactivity of cellulose, torrefaction of cellulose was conducted in a fixed bed reactor at varying torrefaction temperature and residence time. The chemical composition and structural alterations of torrefied cellulose were characterized by elemental analyzer and Fourier-transform infrared spectroscopy (FTIR). The investigation on the pyrolysis behaviors of raw and torrefied cellulose were carried out by using a thermogravimetric analyzer (TGA). The results showed that torrefaction of cellulose mainly proceeded a series of deoxygenation, polycondensation and carbonization reactions. The severe carbonization of cellulose occurred when the torrefaction temperature and residence time were larger than 300°C and 40 min, resulting in the drastic decrease in the pyrolysis reactivity of cellulose. Hence, the optimal torrefaction temperature should not exceed 280°C. |
