Low-pollution coal using agricultural wastes 1998.09.15

The experiment to make use of the molded charcoal which mixed the residue of crops such as corn into coal started in China. Keio University, the University of Tokyo, and the Central Electric Power Research Institute have collaborated with the Chinese side to set up and operate the molding charcoal manufacturing equipment in two cities such as Shenyang City. This molded charcoal is called bio-briquette, which is hardened with high pressure mixed with corn charcoal, wood scraps and slaked lime in coal powder. Slaked lime can fix sulfur content and significantly inhibit SOx generation.
