摘要

在本研究中使用了鹼法紙漿與纖維粉進行實驗，首先分別將樣品加入錐形瓶並加入糖化酵素進行七十二小時糖化過程，過程中每二十四小時測一次糖度，糖化完之後先活化酵母，再分別加入酵母進行七十二小時發酵過程將糖份轉化成乙醇，七十二小時後先分別取樣後放入離心機，離心完後取上清液測糖度並準備進行氣相層析儀分析，先以LC級乙醇進行分析並以圖與數據當檢量標準，最後再分析樣品並藉由檢量標準判斷樣品乙醇濃度。同時證實紙漿纖維為優質生產生質酒精的可行性。

In this article, use alkaline pulp and cellulose powder to experiment. The first is adding the fiber hydrolase and samples into the Erlenmeyer-flask for saccharification process for seventy-two hours. In this process, should conduct brix-measurements every twenty-four hours and activation of the yeast after the saccharification process. Then add yeast for sugar into ethanol for the fermentation process for seventy-two hours. After seventy-two hours, put the samples into centrifuge. Take samples after centrifugation at the top of the clear liquid to test sugar content. First to ethanol were analyzed and to analyze out data as a Calibration standard. Use standards of samples to analysis and calibration to judge by the samples of the ethanol concentration.
