Agglomeration mechanism during biomass carbonization in fluidized bed / Chihiro Ohashi ... [et al.]

Among the various energy conversion technologies of the biomass, the fluidized bed is one of the devices used for its gasification. However, we pointed out the agglomerates of the bed materials surrounding char particles are observed in the bed. In the present study we carried out pyrolysis of Japan...
