Abstract: To improve the fluidization quality of cohesive particles, the traditional perforated plate internals and the remiform internals as well as the new design of the perforated remiform internals were tested with cohesive γ– Al2O3 particles as the experimental material. The experimental results showed that the perforated plate internal was inefficient for improving fluidization quality of cohesive particles, the remiform internal was better than the former. The perforated-remiform internals combine the advantages of two traditional ones and was proved to be the best internals for using in cohesive particles.

Key words: cohesive particle fluidization, internals, perforated remiform internals, disrupting velocity
