... and catalyst circulation rate. In a fluidized bed reactor, the fluidity of catalysts (which is dependent on hydrodynamic parameters such as the size of bubbles) affects the reactivity of the process. We have measured bubble diameter in a fluidized bed of FCA catalyst in order to determine its fluidity...

... Abstract: The use of a two-zone fluidized bed reactor (TZFBR) has been proposed in previous works for several reactions, such as the oxidative dehydrogenation of butane, as a new system for carrying up catalytic oxidation. Although the oxidative dehydrogenation is a reaction of clear interest...

... Abstract The behavior of fluidized bed reactors has been the object of intense research due to its paramount importance in many chemical processes such as Fluidized Catalytic Cracking (FCC) in the petroleum refining industry. Despite the effort, there are many aspects, which are not yet fully...

... for fluidization is one of the principal assumptions underlying the different models of fluidized bed reactors (Grace, 1986; Kunii and Levenspiel, 1969) is used to formulate the model equations of the fluidized bed reactors. Mass and energy balances for the bubble phase The mass balance equations give : where [I...
