| Abstract: | Based on theoretical and experimental study about the formation of double-density fluidized bed with air-dense medium and its separation process, This paper proves it is impossible for current air-dense medium fluidized beds to produce three products. A doubl-density fluidized bed is formed by which the bed structure is specially designed with apyramidal part. |
