英文摘要Clean energies such as solar, wind, and geothermal power have developed rapidly in recent years and they will probably become the dominant energy source in the future. Thus, coal utilization will have to shift from traditional combustion for energy to coal being a source for raw carbon materials. In this paper, anthracite from the Jinzhushan mine located in central Hunan, China, was treated up to 2900 degrees C to examine its chemical, petrographic, and carbon structural evolution. Carbon content increased rapidly from 90.2 to 98.8% (daf basis) when treated up to 1700 degrees C; beyond this temperature the carbon content increased gradually to 100% (daf) at 2900 degrees C. Altered macerals (vitrinite and inertinite) with an amorphous carbon structure were prevalent in samples treated to <= 1500 degrees C. Graphitized components were identified in the anthracite heated to >= 1700 degrees C, as confirmed by micro-Raman spectroscopy and HRTEM. Based on D1 band FWHM versus R-1 plots, the carbon structural evolution of anthracite between room temperature and 1700 degrees C was classified as carbonization, whereas the graphitization process occurred between 1700 and 2900 degrees C. The nanometric polyaromatic rings retained short-range order during carbonization; the condensed aromatic rings remained randomly oriented at the submicron scale. During graphitization, the aligned structural units were able to undergo condensation reactions and de-wrinkle with temperature increase, leading to a marked increase in crystallite parameters L-a and L-c. Most vitrinite and inertinite in the anthracite transformed into graphitic components in samples treated to 2600 and 2900 degrees C, and L-a showed a significant increase whereas L-c only showed a slight increase between 2600 and 2900 degrees C. This study will provide insights for optimizing temperature control strategies during preparation of anthracite-based carbon materials in the future.
