中文摘要 | 由於農業與工廠製造過程所產生的農業廢棄物日益增加,因此農業廢棄物的永續利用逐漸獲得世人關注。這些廢棄物在經過適當的前處理後,成為具有潛力的再生能源。生質酒精(Bioethanol),是一種利用特定微生物將糖發酵所產生的生質資源,其具有高效率且對環境污染程度低。本篇研究報告為生質乙醇概念設計,文中江參考相關文獻及資料,並統整出數據和方程式,在數據和方程式為基礎下,提出一種利用芋頭廢棄物經酵母菌(Saccharomyces cerevisiae)發酵製造酒精的構想。目標工廠經計算後被設計用來製造每年五百萬公升的酒精,足以滿足台灣0.5%的酒精需求。發酵部份是設計由兩個進料槽所組成,將芋頭廢棄物進行稀釋及標準化,之後以通氣生物反應器培養微生物,然後由連續型生物反應器組成兩個串連的系統(好氧接厭氧)進行發酵,使微生物生長及酒精產量提高。 |
英文摘要 | Sustainable utilization of agricultural wastes has gained attention due to increasing amount of waste generated from both field and manufacturing processes. These wastes contain huge potential of untapped energy that can be utilized after undergoing adequate treatment. Bioethanol, a bioenergy source of high efficiency and low environmental impact, is produced through fermentation of sugar by specific microorganisms. In this study, a conceptual design of ethanol production from taro waste by Saccharomyces cerevisiae was proposed based on data and references. An industrial-scale plant was designed to produce 5 million liters ethanol annually accounting for about 0.5% of the annual ethanol demand in Taiwan. The fermentation section of the plant consists of two feed tanks, where taro waste is diluted and standardized, one batch (aerobic) reactor for microbial culture enrichment, and two parallel systems each consisting of two continuous (an aerobic and an anaerobic respectively) reactors for further culture enrichment and ethanol production. |
