摘要

煤炭是目前世界上蘊藏量最豐富的化石燃料，由於石油、天然氣等能源日漸枯竭，因此許多先進國家都開始著手於煤炭的開發。由於燃燒煤炭會造成環境上的污染，所以目前煤炭淨化技術遭受重視。煤炭淨化技術是指減少污染和提高效率的煤炭加工、燃燒轉換和污染控制的新技術。先進的燃煤發電技術中煤炭氣化複循環發電技術(IGCC)在技術成熟性、能源效率、環保性能等方面都最為卓越，以逐漸成為最可行的新燃煤發電技術。如何利用資源再生技術產生的金屬氧化物做為高溫除硫吸收劑為我們研究的重點，本研究以鐵氧磁體法處理含銅金屬模擬廢水之鐵氧磁體污泥之鐵氧磁體作為高溫除硫的吸收劑，去除煤炭氣化複循環發電技術(IGCC)產生出來的硫化氫。本實驗進行鐵氧磁體化法製備鐵氧磁體，作為實驗之吸收劑進行吸收煤炭氣化複循環發電技術(IGCC)所產出的硫化氫，希望未來能利用含重金屬廢水污泥製備成鐵氧磁體，作為吸收硫化氫之潔淨能源，不僅可以將重金屬廢水污泥再次資源利用且還能解決空氣污染的問題。

World primary energy demand increases with increases in population and economic development. Within the last 25 years, total energy consumption has almost doubled. In order to meet this demand, research into new sources of energy as well as improving the efficiency of energy production technologies is being carried out. In both cases, the production of clean energy is very important because of environmental concerns and regulations. Integrated gasification combined cycle (IGCC) processes are considered one of the most efficient and environmentally acceptable technologies for power generation from coal. For the use of these technologies, a highly efficient sulfur removal of the coal-derived fuel gas is needed. Hot gas desulfurization is a crucial issue in the development of the IGCC system. In order to reduce the environmental damage, various hydrometallurgical technologies have been developed to enable the treatment of the wastewater. Many kinds of metals can be removed from wastewater as precipitated ferrites in the ferrite process. Ferrite process was used to treat chromium, copper, nickel and zinc in the electroplate wastewater. Ferrite is a great usefulness in treating the metal-containing wastewater. The objects of the present work are the feasibility of H_2S removal on the Cu-Ferrite sorbent and try to indicate the crystal phase change of the Cu-Ferrite sorbent from the H_2S removal process.
