Abstract：
Large amounts of Chinese herbal medicine wastes(CHMW) are produced in the process of processing and manufacturing traditional Chinese crude medicines. For CHMW, gasification in fluidized bed is a promising option. But it is the difficult to fluidize CHMW particles. It is very common to fluidize these kinds of binmass particles with sand, gives better defined fluidization behavior and a more reliable scale-up. However, not much is kmown about fluidization behavior of CHMW particles in fluidized bed. Therefore, a fluidization characteristic of CHMW was done in the fluidized bed. Minimum fluidization velocity and the effect of bed height of CHMW/quartz sand mixtures on fluidized prooerties in air have been expermentally determined. The results showed that good fluidized could achieve with the additional of quartz sand. The results will be in favorite design and operation of CHMW gasification in fluidezed bed.
