摘要
生質能一直是減碳的重要技術，隨著COP21結束並訂定對未來減碳目標後，生質能的研究將成為取代化石燃料的關鍵。運用生質物的技術非常多，其中熱化學技術可將生質物透過焙燒、裂解、氣化等製程做有效運用。生質物快速裂解技術其料源為固態生物質並產生生質裂解油，屬第二代生質燃料不會造成民爭糧之問題。生質裂解油可應用於加熱、發電、運輸燃料、化學品，最主要功能為提高生質物能源密度約4倍並降低污染物排放。台灣中油公司發展生質熱裂解技術，經累積400公斤生物質快速裂解測試後已可穩定產油，單次進料量可達15kg以上，最高達25kg。在流體化氣體流量60L/min、溫度480~500℃下，木屑產油率可達60%以上，熱值約4000kcal/kg，密度在1.1g/cm^3以上，裂解氣組成CO、CO_2、CH4分別約為5%、3.5%、4%，氫氣與氧氣均為0%。本研究並進行自產之生質熱裂解油試燒共計測試約140L，以紅外線測溫槍最高可量得910℃。

Biomass utilization is a very important carbon reduction technology. After the COP 21 set the target about carbon reduction in the future, bioenergy is the key point to replace fossil fuel. There are many technology to use biomass, and thermochemical technogy convert biomass effectively by torrefaction, pyrolysis, gasification and combustion. Biomass fast pyrolysis technology convert solid biomass to biomass pyrolysis oil which is the second generation biofuel that won’t compete the food with human being. Heating, power generation, transport fuel and chemical are the way to use biomass pyrolysis oil, and the most important value of biomass pyrolysis oil is to increase energy density to 4 times and reduce pollutant emission. CPC, Taiwan develop biomass pyrolysis technology and test 400kg feedstock and the process stability is good. We feed 15kg biomass to pyrolysis unit in single experiment and up to 25kg. The fluidized gas rate is 60L/min and reactor temperature is 480~500℃, and the yield, HHV, density are 60%, 4000kcal/kg and 1.1g/cm^3, respectively. The composition of syngas are 5% CO, 3.5% CO_2, 4% CH_4, O_2 and H_2 are 0%. We also conduct 140L pyrolysis oil combustion test and measure the flame temperature up to 910℃ with Infrared Thermometer.
