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. fl uidised 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 a t 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 c annot be determined by experiments to be predicted. (C) 2001 Elsevier Scien ce BN.
