Modeling the effect of coke deposition in a heat integrated ethanol reformer

This modelling effort is unique is elucidating the spatial distribution of catalytic activity in a reformer, evolving owing to varying rates of local catalyst deactivation. Moreover, the simultaneous variation of catalyst activity and effective diffusivity have been modelled, which has never been investigated in the past. Conclusions from this work counter the often-maintained belief that enhanced heat transfer always enhance the reformer performance. We expect the broad conclusions of the modelling effort to direct future catalyst development.
