Modelling of a two-zone fluidised bed reactor for the oxidative dehydrogenation of n-butane

A reactor model is proposed as a means of representing an in situ redox fluidised bed reactor for the oxidative dehydrogenation of n-butane with a V–Mg–O catalyst. The model describes a reactor where the hydrocarbon is fed at some intermediate point and the catalyst oxidation and reduction occur in different zones within a fluidized bed. This model allows the behaviour of the reactor to be understood and the effect of operating parameters that cannot be determined by experiments to be predicted.
