| Summary: | 碩士 === 國立臺北科技大學 === 化學工程與生物科技系化學工程碩士班 === 107 === This study aims to develop a steady-state simulation model for the production of bio-oil from fast pyrolysis (FP) of lignocellulosic biomass. The production involves a hydrodeoxygenation (HDO) process to refine the bio-oil to provide low oxygen content end products. The FP technology for biomass has been widely studied and used in practice. However, due to the variability of biomass composition and the complexity of bio-oil composition, as yet no detailed theoretical steady-state process model has been developed to predict the composition of bio-oil from pyrolysis. This study takes advantage of the experience and findings in the literature to establish a method of characterizing biomass. In addition to the decomposition of biomass into cellulose, hemicellulose and lignin, extractives are added to expand the region of biomass characterization. Deoxygenated bio-oil is then produced through corresponding pyrolysis kinetic reactions and the HDO process. With a detailed steady-state simulation model, the optimal operating conditions for FP can be found by analyzing the effects of each operating variable on the process. The results are expected to provide useful insights for future research and development.
