The main individual reactions that take place in the reformer (e.g., reactions (1), (2) and (5)) will be considered separately from the overall autothermal reaction for two reasons. First, in ATR the reactor can be considered as two plug-flow reactors in series (1) a very fast POX reaction occurs at the top of the catalyst bed and utilizes a small portion of the bed and (2) a slow SR utilizes the remainder of the reactor bed. Therefore, an optimal ATR catalyst must have excellent SR eatalytic properties. Second, there may be situations in which liquid fuels are reformed using only these individual reactions e.g., diesel fuel may be reformed using only SR (reaction (2)) or only by POX (reaction (1)).

When the reactors are of equal volume, the overall conversion is independent regardless of which reactor precedes. However, generally, the CFSTR should precede the plug flow to minimize the total reactor volume. Figure 5-37 shows the total residence time of the CFSTR and plug flow reactors in series. 

The final sequence we shall consider is a CSTR and plug-flow reactor in series. There are two ways in wlricb this sequence can be arranged (Figure...

Danckwerts Mixing vessel and plug flow reactor in series. Both orders of the apparatus A and B give identical residence time distribution from [92]. 

This model accounts for fuel atomization and vaporization, partial oxidation, steam reforming, and anode exhaust combustion. It is asumed that the partial oxidation reaction is very fast and occurs at the top of the catalyst bed along with fuel atomization and vaporization. It is also assumed that the steam reforming initiates after all O2 is consumed in the partial oxidation reaction. Therefore, the reactor will initially be considered as two plug-flow reactors in series. Figure 2 and 3 depict the inlet conditions for the ATR model and results from the model, respectively.
