【 摘 要 】

The project proposes a completely ecologically and energetically closed waste-free technology for gasification of pulverized coal waste in a suspended slag layer, producing a conditioned synthesis gas, simultaneous reduction and recovery of metal from ash and slag, and also obtaining a highly porous aluminosilicate slag (microspheres) suitable as lightweight aggregate, paints and coatings with low thermal conductivity, as well as adsorbent and other applications.
