This Small Business Innovative Research (SBIR) Phase I project will address large scale production of fullerene materials in an ecologically benign manner. Presently, fullerene manufacturing is based on a synthesis of soot from an evaporated graphite rod and a dissolution of the soot in an organic chemical solvent to extract the fullerene. Synthesis of soot is energy intensive and impractical for large scale production, while the organic chemical process is environmentally toxic and hazardous. This project will extract fullerene from fullerene-containg coal. The process will involve (i) demineralization and elimination of impurities in the coal and (ii) extraction of fullerenes by sublimation. If proven feasible as an economical and ecologically benign process, it could be commercialized to meet the presently growing demand for fullerene materials.

这个小型企业创新研究（SBIR）第一阶段项目将以生态友好的方式解决富勒烯材料的大规模生产问题。 目前，富勒烯的制造是基于从蒸发的石墨棒合成烟灰并将烟灰溶解在有机化学溶剂中以提取富勒烯。 烟尘的合成是能量密集型的，并且对于大规模生产是不切实际的，而有机化学过程对环境有毒且有害。 该项目将从含富勒烯的煤中提取富勒烯。 该过程将涉及（i）脱矿物质和消除煤中的杂质，以及（ii）通过升华提取富勒烯。 如果被证明是一种经济和生态友好的方法，它可以商业化，以满足目前日益增长的需求富勒烯材料。
