Carbonation of rawred mud produced by aluminium refineries and a chemically and physically neutralized red mud (Bauxsol™ has been carried out to study the capacity of these wastes to capture carbon dioxide. After only 5 min of carbonation of raw red mud, total alkalinity dropped 85%. Hydroxide alkalinity was almost totallyconsumed, carbonate alkalinity dropped by 88%, and bicarbonate alkalinity increased to 728 mg L−1. After 24 min carbonation, the bicarbonate alkalinity reached its maximum value of 2377 mg L−1, and hydroxide and carbonate alkalinity were virtually absent. After 30 and 60 min carbonation, bicarbonate alkalinity started to decrease slightly as the pH of the slurry increased. After 5 min carbonation of Bauxsol™, total and bicarbonate alkalinity dropped 89% and 9%, respectively. After 20 min carbonation, bicarbonate alkalinity dropped another 11%, but after 30 min carbonation bicarbonate alkalinity increased 26% to levels found in the original Bauxsol material, and pH was stable. Based on these experiments, a calculation of the amount of carbon dioxide that could be removed annually at aluminium refineries in Australia is potentially 15 million tonnes, and suggests that further studies are necessary to maximize this carbon removal process. Furthermore, carbonation produces a product, which can potentially be used in other industrial and agricultural activities to remove toxic metals and nutrients. |

| 為了研究紅泥原料和用化學(xué)和物理方法中和的紅泥（BauxolTM）的碳捕獲能力對這兩種廢物進行了碳化處理。對紅泥原料只經(jīng)過5分鐘的碳化后，其總堿度就降低了85%。其中氫氧化物堿度基本上被完全消耗了，碳酸鹽堿度降低了88%，重碳酸鹽堿度上升帶728mg/L。碳化24分鐘后，重碳酸鹽堿度達到其最大值2377mg/L，氫氧化物堿度和碳酸鹽堿度就消失了。碳化30分鐘和60分鐘后，隨著泥漿的pH的上升重碳酸鹽堿度開始稍微減少。對Bauxsol™進行5分鐘碳化后，總堿度和重碳酸鹽堿度分別降低了89%和9%。碳化20分鐘后，重碳酸鹽堿度又減低了11%，但是30分鐘后重碳酸鹽堿度增加了26%達到Bauxsol™的初始重碳酸鹽的堿度水平而pH值沒變化�；谶@些實驗，我們計算出澳大利亞的煉鋁廠每年的潛在二氧化碳消耗量為15000000噸，我們建議應(yīng)該進行深入的研究來使二氧化碳的消耗量最大化。此外，碳化產(chǎn)生了一種產(chǎn)品可能在其他工農(nóng)業(yè)活動中用了清除有毒金屬元素和營養(yǎng)素。 |
