摘要:In this paper, the pyrolysis characteristics of sucrose biomass were investigated in a tubular reactor at different temperatures and also using a thermogravimetric analyzer at the heating rate of 10 degrees C min(-1) from room temperature to 1200 degrees C. The gas products in the pyrolysis process were measured using an Agillent 6890N GC analyzer. The results showed that the temperature greatly affected the product yields. The pyrolysis gas consisted of a major amount of CO, CO2, H-2, and CH4, and its yield increased greatly with increasing temperature. Tars occurred mainly at 200-300 degrees C under isothermal measurements in tubular reactor. The amounts of solid residue and tars decreased with increasing temperature. The presence of CaO responsible for the pyrolysis phase was shown to increase the conversion of sucrose and capture the CO2 produced. The kinetic analysis indicated that the reaction order model (first order) predicted accurately the conversion of 0.102-0.901 during the isothermal pyrolysis of sucrose in tubular reactor, and Arrhenius parameters and prediction of the pyrolysis time were obtained from isothermal kinetic results.
