The influence of interparticle forces (IPFs) on the hydrodynamics of a gas-solid fluidized bed was experimentally investigated with the help of a polymer coating approach. The results showed that the presence of IPFs in the bed can considerably change the hydrodynamic parameters. The tendency of the fluidizing gas passing through the bed in the emulsion phase increased with IPFs in the bubbling regime. The performance of a fluidized bed reactor was then studied through simulation of a reactive catalytic system using three different hydrodynamic models: (a) a simple two-phase flow model, (b) a dynamic two-phase flow model, and (c) a dynamic two-phase flow model, integrating the effects of superficial gas velocity and IPFs. The simple two-phase flow model was found to underestimate the reactor performance for catalytic reaction most likely due to the oversimplified assumptions involved in this model. Also, the simulation results showed that modification of the bed hydrodynamics due to IPFs resulted in a better performance for a bubbling fluidized bed reactor. This suggests that the hydrodynamic models should take into account the effects of superficial gas velocity and variation in the ratio of the magnitude of IPFs/hydrodynamic forces, due to any operational reason, to yield a more reliable evaluation of the performance of the fluidized bed reactor.

C., Ed.; Plenum: New York, 1980; p 561.The oxidation of 1-butene and butadiene to maleic anhydride was tested with an integral reactor with vanadiumphosphorus mixed oxides prepared by different methods and presenting different activities and selectivities. The data were analyzed by utilizing a Langmuir-Hinshelwood type rate expression derived under differential conditions. At high partial pressure, competition between 1-butene and butadiene for the same active centers leads to a decrease in the rate of formatlon of maleic anhydride. This competitlon does not affect the rates of formation of methyl vinyl ketone, acetaldehyde, and carbon oxides. Emphasis is made on the necessity of operating with oxygen-nriched air in order to avoid the negative effect of the reactant on the rate of maleic anhydride formation.
