摘要

自从发现煤衍生的碳泡沫材料以来,这些材料在高价值应用中的采用显著增加,特别是在航空航天工业中。煤衍生碳泡沫材料具有优异的热性能和机械性能,使其成为建筑和建筑等大批量应用的最佳选择。然而,它们在此类应用中的广泛采用受到当前批量或半连续处理技术的限制。本研究介绍了一种采用直接挤压工艺连续生产碳泡沫材料的创新方法。沥青煤(匹兹堡8号和白森林)在不同的进料速率,温度和挤压速度下连续挤压,以生产碳泡沫材料。通过热重分析(TGA)、差示扫描量热法(DSC)、极限/近似分析和光学显微镜对所得绿色泡沫进行了表征。这项研究不仅成功地证明了塑化煤的可挤出性,而且还揭示了它们的性能有望与批量加工的煤衍生碳泡沫材料相当。

Continuous Production of Carbon Foam from Carbon Ore

Continuous Production of Carbon Foam from Carbon Ore
Since the discovery of coal-derived carbon foam materials, there has been a significant increase in the adoption of these materials in high-value applications, particularly within the aerospace industry. Coal-derived carbon foam materials offer exceptional thermal and mechanical properties, positioning them as an optimal choice for high-volume applications such as building and construction. Yet, their broader adoption in such applications is hindered by the limitations of the current batch or semi-continuous processing techniques. This research introduces an innovative method for continuous production of carbon foam materials using a direct extrusion process. Bituminous coals (Pittsburgh No 8 and White Forest) were continuously extruded at varying feed rates, temperatures, and extrusion speeds to produce a carbon foam material. The resultant green foams were characterized via thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), ultimate/proximate analysis, and optical microscopy. This study not only successfully demonstrated the extrudability of plasticized coal using a commercial bench-scale extrusion system but also revealed that their performance is expected to be comparable to that of batch-processed coal-derived carbon foam materials.
