Anthracite latter in two or three sizes, all three being above in (38 mm) size on round-hole screens. High grade (HG) and ultra high grade (UHG) anthracite are the highest grades of anthracite coal. They are the purest forms of coal, having the highest degree of coalification, the highest carbon count and energy content and the fewest impurities (moisture, ash and volatiles). High grade and ultra high grade anthracite are harder than standard grade anthracite, and have a higher relative density. An example of a chemical formula for high-grade anthracite would be CHONS, representing 94% carbon. UHG anthracite typically has a
Carbon capture and storage (timeline) intent to establish the Clean Energy Commercialization Centre. CECC aims to accelerate the development in China of clean coal conversion technologies and the creation of associated value chain investment opportunities through the commercialization of key technologies and coordinated management of large scale demonstration projects which primarily use coal as feedstock for fuel production, chemicals manufacturing and power generation. "Carbon Capture Journal" focuses on industrial carbon capture from power stations and industrial plants and carbon dioxide underground storage, including new technology, policy and projects. Since launching the website in May 2007, it has been actively sought out by the carbon capture
