BRIAN and BEAVE~~TOCK do not make it clear if their simpler two-step model is also compatible with the observations of GILLILAND et al. It is concluded that the model used by BIUAN and BEAVER-STOCK does not correspond to the mechanism of absorption of carbon dioxide into solutions of amines, nor, a

The successive formation of gas bubbles on the gas distributor of a multi-orifice plate in two-dimensional air-fluidized beds was studied both theoretically and experimentally. A brief theory for the initial bubble formation, which reflects the effects of fluidized particles, was developed based on
## AbstracbIn gas-fluidized beds bubbling starts when the voids formed by the oscillating bottom layer of the bed exceed a minimal size. The so-called vibration criterion derived predicts the porosity at the bubble point in close agreement with the experimental data. Comparison of the other criter
