Reactivity of Carbon-Carbon Composites

本项目研究沥青-焦炭复合材料的反应性，目的是最大限度地减少铝冶炼过程中阳极的氧化碳损失。这样的碳损失约占冶炼总碳消耗量的15%，它的减少除了有助于减少温室气体排放外，还将提供可观的经济效益。在本项目中，将研究焦炭焙烧和复合焙烧温度对阳极微观结构与在氧气和二氧化碳中的反应活性的影响，并确定最佳工艺条件，以使冶炼过程中活性碳损失最小。

This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temperatures on the relationship between anode microstructure and reactivity in oxygen as well as carbon dioxide will be investigated, and optimum process conditions determined for minimum reactive carbon loss during smelting.
