中文摘要 | 鋼鐵工業會產生大量之二氧化碳,且鋼鐵製造過程中產生之鹼性廢棄物(例如:轉爐石與鹼性冷軋廢水),需經過妥善處理後,才能再利用於土木工程或排放至水體。本團隊整合廢棄物碳酸化反應與旋轉填充床程序,為國際上首創之整合式創新技術,目前已證實超重力旋轉填充床可有效提升轉爐石捕獲二氧化碳效率,且反應時間、溫度與壓力等操作參數,也相對較傳統反應器(例如:漿體反應器與壓力鍋)優越。據此,本研究目的包括:開發新穎二氧化碳捕獲與爐渣安定化程序,提升爐渣吸附容量及再利用效能;透過材料物化分析、電子顯微鏡與X光繞射分析等,評估反應後轉爐石再利用之潛力。 |
英文摘要 | A great amount of CO_2 and alkaline wastes have been generated from iron and steel making industry for many years. The industrial wastes such as basic oxygen furnace slag (BOFS) and cold-rolling mill wastewater (CRMW) should be treated and stabilized before discharging or reutilization. It was noted that the alkaline wastes generated from steelmaking industry could be utilized for CO_2 capture via carbonation process. Our study showed that CO_2 capture by accelerated carbonation of BOFS in a rotating packed bed (PRB) was found to be superior to that in the traditional reactors due to the relatively short reaction time at ambient temperature and pressure. The objectives of this study were to (1) evaluate the performance of using the CRMW as the liquid phase for increasing the overall carbonation efficiency and reducing the fresh resource consumption; (2) characterize the reaction product using thermo-chemical analyses, scanning electron microscope (SEM) and X-ray diffraction (XRD); and (3) assess the potential for utilization of carbonated BOFS as Green Cement. |
