氣泡式流化床生質物氣化系統簡介

生質物不同特性可應用於氣化、燃燒、裂解並產生相關化學品，氣化後之生質合成氣可應用於加熱、發電、或轉換為運輸燃料與化學品。各種技術之產品組成有所不同，氣化主要產品為合成氣（CO、CO_2、CH_4、H_2）、油（有機酸、焦油）、生質碳，焙燒主要產品為固體與氣體，裂解則以液體（裂解油）為主氣固體為輔。中油綠能所（CPC GTRI）目前發展生質熱裂解與氣化技術之產品主要應用為替代燃料油並有機會產相關化學品，且在低成本料源情況下可較傳統石化燃料便宜，裂解與氣化已總計測試達150小時以上，利用開發熱裂解技術之經驗與設備修改後，可進行初步氣化測試評估，為瞭解現有技術瓶頸，本文主要就本公司生質物氣化技術現況做介紹，實驗參數主要參考EPI gasification之結果進行調整，並可穩定進料木屑3kg/hr達5小時以上，在空氣流量60L/min可穩定控制於750度左右，CO與CO_2大約為13%與15%，氫氣約2%，CH_4約6%。由於生質物氣化會有大量焦油產生，本系統未來將朝生質物觸媒氣化測試平台方向規劃，並結合國內相關研究單位進行研究以提昇技術能量。

Biomass with different characteristics can apply at thermochemical process as gasification, combustion or pyrolysis and can make biochemical. The syngas from gasification can be used to heating, electricity, transform to transport fuel chemical. The main product from gasification are syngas (CO、CO2、CH4、H2), oil (organic acid, tar) and biochar are byproduct. The main product from torrefaction is gas and biochar. The main product from pyrolysis is bio-oil. GTRI in CPC, Taiwan recently develops biomass gasification and pyrolysis process (test over 150hrs) to replace fuel oil and make biochemical. The fuel cost is lower than fuel oil when biomass is cheap. By revamping the existing pyrolysis unit and experience, we conduct biomass gasification as a preliminary stage test. This article make introduction to GTRI biomass gasification which take EPI gasification as reference and make adjustment. We feed the sawdust at steady rate 3kg/hr with air velocity 60L/min and control temperature at 750℃. The syngas compositions (CO, CO2, H2, CH4) are 13%, 15%, 2%, 6% respectively. For there is large amount of tar produce during gasification, our system will schedule as a biomass catalytic gasification testing platform and cooperate with other research institute in Taiwan.
