【 摘 要 】

Annually coal-fired heat-and-power plants produce up to 40 million tons of ash and slag in Russia, while the already accumulated in the ash-dumps waste exceeds 1.5 billion tons. In Russia alone heat power plants' ash-dumps occupy over 20 thousand km2 of land area. Ash and slag waste reclamation volume in Russia doesn't exceed 6 % of of their annual accumulation (annually only 1.5-2.1 million tons are recycled), while other countries recycle 50-100 % of ash and slag waste. Russia's main coal-mining region is the Kuznetsk coal basin. The importance of the suggested fly ash geosorbent technology is in the fact that its use will make it possible to recycle and reclaim the already accumulated ash and slag waste, but the newly produced waste as well. Thus, the objective of the project in question is the study of the use of heat power plant fly ash as a gas-adsorbing agent in the chemical industry, and as a means to extract industrial oils and lubricants out of waste water.
