Red mud was investigated in triglyceride transesterification with a view to determine its viability as a basic catalyst for use in biodiesel synthesis. The effect of calcination temperature on the structure and activity of red mud catalysts was investigated. It was found that highly active catalyst was obtained by simply drying red mud at 200 degrees C. Utilization of red mud as a catalyst for biodiesel production not only provides a cost-effective and environmentally friendly way of recycling this solid red mud waste, significantly reducing its environmental effects, but also reduces the price of biodiesel to make biodiesel competitive with petroleum diesel.
研究了赤泥在甘油三酯酯交换反应中的应用,旨在确定其作为生物柴油合成用碱性催化剂的可行性。考察了煅烧温度对赤泥催化剂结构和活性的影响。结果表明,赤泥经 200℃简单干燥即可得到高活性催化剂。将赤泥用作生物柴油生产的催化剂不仅为这种固体赤泥废物的回收提供了一种经济有效且环保的方法,可显著降低其环境影响,而且还降低了生物柴油的价格,使其具有与石油柴油竞争的能力。
