Anthracite Mohs scale), its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter. It is also free from included soft or fibrous notches and does not soil the fingers when rubbed. Anthracitization is the transformation of bituminous coal into anthracite. The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis. The heat content
Carbon capture and storage capture projects include: The Shanxi International Energy Group (SIEG) is working to construct a 350 MW super-critical coal-fired power plant in Taiyuan, Shanxi province in China. Set for construction in the 2020s, this plant will capture carbon dioxide using oxy-fuel combustion, aiming for the capture of over 2 million tons of carbon dioxide per year. SIEG has been working with the US-based company Air Products since 2010 to perform feasibility testing and adapt its oxy-fuel technology to a proposed plant design. Captured carbon dioxide will be both sequestered and used for other applications. This project has also been included in
