中文摘要 | 本研究以台灣南部之刺竹(Bambusa stenostachya)與長枝竹(B. dolichoclada)為原料,應用快速熱裂解技術產製生質油,並分析其基本性質,評估其未來作為燃油或其它相關產品應用條件。研究結果顯示,刺竹裂解油之高熱值(HHV)為13.92 MJ/kg,長枝竹裂解油為14.87 MJ/kg,作為替代能源所需熱值略顯偏低,需透過改質技術提昇其應用於能源之效益。然刺竹與長枝竹生質油透過氣相層析質譜分析儀(GC-MS)分析結果,具有超過80餘項豐富之化學組成分,長枝竹生質油以酚類超過50%佔最大比例,刺竹生質油主要成分為酚類、羧酸類與酮類。此結果顯示,兩種竹生質油均具有替代化石燃料,提供生產化學產品之極佳潛力。 |
英文摘要 | In this study, thorny bamboo (Bambusa stenostachya) and long-branch (B. dolichoclada) bamboo were integrated as feedstock to produce pyrolysis liquid (bio-oil) using fast pyrolysis technology, and the basic properties of the bio-oils were analyzed. Results showed that the higher heating value (HHV) of both bio-oils were 13.92 MJ/kg for thorny bamboo and 14.87 MJ/kg for longbranch bamboo, and both HHVs were relatively low for use as bioenergy. The bio-oils need to be reprocessed using upgrading technologies to promote the efficiency of energy utilization. However, both bio-oils were analyzed by gas chromatography mass spectrometry (GC-MS) and were shown to contain more than 80 different organic compounds with multifunctional groups. The major compounds in the bio-oil of long-branch bamboo were phenols with the largest proportion of >50%, and those of thorny bamboo included good distributions of phenols, carboxylic acids, and ketones. Both bio-oils are great potential resources beyond just a fossil fuel to provide various chemical compounds. |
