  • Synergistic Effect of Coal Blends on Thermoplasticity

    Sep 16 2006 · To maximize the conversion of low-quality coal into good coke we investigated the thermoplasticity of various binary blends of caking coals with slightly or noncaking coals using a dynamic viscoelastic technique with a temperature-variable rheometer. Coal blend samples were prepared by mixing two coals (1 1 by weight) which were heated from room temperature to 600 °C at a rate of
