Popis: The spouted-bed reactor represents an interesting alternative to pyrolysis as compared with conventional fluid beds due to its better performance in handling coarse and irregular materials, requiring lower fluidizing flow rates and providing intense thermal contact. The fluid dynamics of a mixture of sand and sugarcane bagasse in a spouted bed was investigated. Since this process involves a mixture of solids of different sizes, shapes, and densities, particle segregation was also analyzed. The results provided significant insights about the segregation phenomenon which may cause severe operating problems during pyrolysis. Various mixture compositions were identified in which the particles exhibited good circulation in the bed.
