"Properties of \"white coal\"

Thread Content

\"White coal\" is a pollution-free, efficient, and energy-saving fuel. It is obtained by condensing and recovering the waste gases produced during petroleum cracking, and then undergoing a series of chemical treatments (purification, detoxification, polymerization, and solidification) to yield white powdery particles that contain only carbon and hydrogen compounds; such particles do not contain sulfides or any chemicals harmful to human health. “Before being transported for sale, \"white coal\" needs to be press-formed and packaged. The standards for good white coal are as follows: (1) White coal has lower mechanical strength and thermal stability compared to coke ； (2) The volatile components of white coal are higher than those of coke, and its ash melting point is lower than that of coke ； (3) The fixed carbon content of white coal is higher than that of coke. (4) Moisture content: 3.2% ； Ash content: 5.89% ； Volatile matter 8.3% ； Particle size: 30–80 mill; mechanical strength is average. This post was last edited by Captain Yang on 2008-5-22 10:50.]
