Propane autothermal

Faria et al. [28] studied the propane autothermal reforming on Ce02/Al203-based Pd catalysts. They observed a distinct reaction occurring in the presence of Ce02. 

Experimental results concerning the development of a small-scale 1 kW autothermal reformer of propane were reported by Rampe et al. [76]. In the proposed reactor, two reactions occur on a metal honeycomb structure coated with platinum. Air and water are mixed before they are fed to the reactor in counterflow to the product gas outside the reactor wall, where the water is vaporized and the steam and air are heated up. Then, they are mixed with propane at the bottom of the reactor. It was verified that the preheating operation mode led to about a 4% higher efficiency, since the higher inlet air temperature causes a higher temperature level in the reaction zone, resulting in improved kinetics of the reforming reaction.

Rampe et al. developed a monolithic autothermal propane reformer with feed gas pre-heating functions (see Figure 7.4). The reactor had a thermal power output of up to 1.7kW while the volume of the monohth was 283 cm [151]. The reactor was operated at a high O/C ratio of 1.33, and S/C ratio of 1.0.
