中文摘要 | 本研究開發一創新快速熱解生質原料轉成生質油之雛型機,系統中包含單擠壓推拔型導螺桿,利用變頻器控制馬達轉速,再搭配鏈條傳動導螺桿,以輸送生質原料並同時進行熱解。本裝置簡單、效率高、廉價且易放大。另外,以樟樹作為生質原料進行本裝置之初步測試,實驗結果得知,欲獲得最高生質油產率時,對於粒徑小於0.85mm之生質原料,最佳之擠壓螺桿轉速為20rpm,熱解溫度為470℃;又,當粒徑為0.85mm~1.18mm時,最佳之擠壓螺桿轉速為20rpm,熱解溫度為500℃;另,當粒徑為1.18mm~1.70mm時,最佳之擠壓螺桿轉速為40rpm,熱解溫度為500℃。 |
英文摘要 | A prototype fast pyrolysis reactor for converting biomass (agriculture and forestry wastes) into bio-oil has been developed in this study. In the developed system, a novel reaction chamber consisting of a single tapered screw extruder which is chain-driven by a motor with adjustable rotational speeds was designed for simultaneously feeding and pyrolyzing the biomass. This particular reactor has merits of simplicity, high processing capability, easy to scale-up and also relatively low cost. In addition, Trial runs of the developed fast pyrolysis reaction system have been conducted for camphor trees, and the results indicate that for grain size below 0.85mm, the optimal pyrolysis temperature and rotational speed to reach peak bio-oil yield are 470℃ and 20rpm, respectively, whereas 500℃ and 20rpm are for 0.85~1.18mm grain size range, and 500℃ and 40rpm are for 1.18~1.70mm grain size range. |
