| 中文摘要 | 沼氣中存在的硫化氫會導致設備腐蝕,此外硫化氫也會傷害人類和動物的健康,所以沼氣在應用之前必須先移除與淨化,才能作為兼具環保與安全的再生能源。本研究設計一固態脫硫裝置,以氧化鐵顆粒作為脫硫劑,改變不同的沼氣流量與脫硫柱中氧化鐵顆粒高度進行沼氣脫硫試驗,檢測硫化氫濃度隨測試時間的變化,分析探討沼氣其硫化氫去除率。由試驗結果顯示,固態脫硫柱中氧化鐵顆粒高度越高,沼氣通過的路徑越長,吸附的反應效果越好,此外硫化氫去除效率隨脫硫時間的增加而減少。在沼氣流量25ℓ/min、氧化鐵顆粒高度15.3cm及脫硫時間70分鐘方式下,平均脫硫效率為95.16%。 |
| 英文摘要 | The contained hydrogen sulfide in the biogas would lead to corrosion of the metal equipment. In addition, the high concentration of hydrogen sulfide can also harm the health of humans and animals. As for renewable energy for both environmental protection and safety, the biogas must be removed and purified before being used. In this study, a solid-state desulfurization device was designed. The biogas flows through the bottom of the transparent desulfurization column which is made of acrylic glass. The iron oxide particles were placed in the desulfurization column as desulfurizer. The biogas desulfurization test was carried out by changing the different biogas flow and the height of the iron oxide particles in the desulfurization column, the change of the hydrogen sulfide concentration with the test time was measured and the removal rate of hydrogen sulfide in the biogas was analyzed. The experimental result shows the removal rate of hydrogen sulfide decreases with the increase in biogas flow, and it also increases with the iron oxide particle height in the desulfurization column. A longer stagnation within the desulphurization column improves the removal efficiency of hydrogen sulfide. In addition, the removal efficiency of hydrogen sulfide gradually decreases with an increased desulfurization period. The average desulfurization efficiency was 95.16% at a biogas flow of 25 ℓ/min, iron oxide particle height of 15.3 cm and desulfurization period of 70 minutes. |
