Coal tar the European Chemicals Agency. The exact mechanism of action is unknown. Coal tar is a complex mixture of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds. It is a keratolytic agent, which reduces the growth rate of skin cells and softens the skin's keratin. Coal tar is produced through thermal destruction (pyrolysis) of coal. Its composition varies with the process and type of coal used – lignite, bituminous or anthracite. Coal tar contains approximately 10,000 chemicals, of which only about 50% have been identified. Components include polycyclic aromatic hydrocarbons (4-rings: chrysene, fluoranthene, pyrene, triphenylene, naphthacene, benzanthracene, 5-rings: picene, benzo[a]pyrene, benzo[e]pyrene,
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
