With the recent concern over depletion of high-quality coking coal used for coke production, it is desirable to develop a simple method convert low-grade coals with poor properties into coals. In this study we have focused on possibility that polymerization reactions caused by recombination coal-inherent radicals may occur when heated, which can deteriorate softening and melting coal. Aiming at...

This study reviews waste water characterization of iron and steel industry and treatment procedures involved in these industries. The production of iron from its ores involves powerful reduction reaction in blast furnaces. Cooling waters are inevitably contaminated with products especially ammonia and cyanide. Production of coke from coal in coking plants also requires water cooling and the use...
