An integrated fuel processing system for different fuels for mobile and small-scale stationary power units up to a range of 5 kWe was developed by the IMM [44]. A complete fuel processor for 5 kW (Figure 23.5) was set up for use of isooctane as fuel. 

Moon et al. [59] presented a breadboard fixed-bed fuel processor for isooctane, which was composed of an ATR and high-and low-temperature shift reactors. The fuel processor was applied for testing different catalysts. A NiO/CaO/Al203 catalyst performed equivalent to a Ni/Fe/MgO/AlaOs catalyst for the autothermal reforming reaction. 

A microstructured monolith for autothermal reforming of isooctane was fabricated by Kolb et cd. from stainless steel metal foils, which were sealed to a monohthic stack of plates by laser welding [73]. A rhodium catalyst developed for this specific application was coated by a sol-gel technique onto the metal foils prior to the sealing procedure. The reactor carried a perforated plate in the inlet section to ensure flow equi-partition. At a weight hourly space velocity of 316 L (h gcat). S/C 3.3 and O/C 0.52 ratios, more than 99% conversion of the fuel was achieved. The temperature profile in the reactor was relatively flat. It decreased from 730 °C at the inlet section to 680 °C at the outlet. This was attributed to the higher wall thickness of the plate monolith compared with conventional metallic monolith technology. The reactor was later incorporated into a breadboard fuel processor (see Section 9.5).
