Plate catalytic afterburner

The reformer unit was designed as a joint-part coupling the catalytic afterburner and the reformer layer in a sandwich-design, with the catalytic coated reformer substrate located between two burner plates (Figure 10). A commercial oxidation catalyst was used as burner catalyst, arranged as randomly packed bed above and below the reformer unit.

Figure 5.53 shows the flow scheme of a 10-kWei diesel fuel processor/fuel cell system based on steam reforming, as designed by Cutillo et al. (443). The energy required to run the endothermic reaction was generated in a directly coupled catalytic afterburner, which could be realised as a plate heat-exchanger, as described in Section 5.1. The S/C ratio fed to the steam reformer was substantially higher compared with the system discussed above in order to prevent coke formation.
