A stochastic model based on Markov chain is proposed to describe the gas residence time distribution and contact time distribution in multistage fluidised beds. The Kolmogorov-Feller equations are solved by Laplace transform and subsequent numerical inversion. The effects of flow fluctuations on the
Perforated plates were added to section the column and a fluidised bed was modified as a counter-current staged fluidised bed. The bed types and particle residence time were investigated in single-stage and two-stage fluidised bed systems. A stable bed (column I.D. = 3 cm, plate opening ratio = 0.2)
