摘要：
Sugar cane bagasse is an agro-based residue that is a very good feedstock for energy recovery processes. The aim of this study was to use ASPEN Plus v8.8 to develop thermodynamic simulation models for energy-recovery from sugar cane bagasse and to predict product yield and composition based on the inherent characteristics of the feedstock and other process factors. Two simulation flowsheets were developed for energy recovery from sugar cane bagasse: one for a pyrolysis process and the other for a combined pyrolysis-steam reforming process. The simulation predictions revealed a very good yield of bio-oil (63.4%) from sugar cane bagasse. The oil was composed of hydrocarbons of different lengths, aromatic compounds, and pyrolytic water (8.1%). For the pyrolysis steam-reforming simulation, the optimal conditions were a temperature range of 600-700 degrees C, pressure of 1 atm, and steam-to-feed ratio (STFR) of 10 kg kg(-1). Factor interactions were examined from response surface plots. A theoretical model for the prediction of hydrogen yield was also developed by regression, with a good R-2 value. Analysis of variance (ANOVA) results revealed that the model was significant but pressure was not a significant factor in the steam reforming process.
