Abstract:The mathematic models of the one-dimension and two-dimension pseudo-homogeneous fixed-bed reactor have been established based on the kinetic of toluene alkylation with methanol. Toluene conversion, mole fraction of every component, reaction temperature can be achieved from the simulation of one-dimension pseudo-homogeneous reactor. In order to have a more reasonable understand for reactor, heat transfer, mass transfer, reaction and fluid dynamics should be considered as well. In the two-dimension reactor models, not only the distribution of toluene conversion and reaction temperature along the reactor axial, but also the distribution along the reactor radial can be achieved. The results of the simulation for two dimension reactor indicate that the fluid dynamics have an important impact on the reactor.
