Ferrandon and Krause investigated the effect of the catalyst support on the performance of rhodium catalysts wash-coated onto cordierite monoliths for autothermal reforming of gasoline [245]. The samples contained 2 wt.% rhodium on gadolinium/ceria, and lanthanum-stabilised alumina [245]. The latter sample showed higher activity and superior selectivity. Only 30 ppm of light hydrocarbons (C > 1) were detected. However, the sample also had higher surface area and rhodium dispersion. Both samples showed stable performance for more than 50-h test duration. 

Gadolinium stabilised ceria was used as support for a platinum catalyst for autothermal reforming of gasoline and diesel. The catalyst contained only 0.5 wt. % platinum. It was operated at temperatures exceeding 800 °C [256]. However, stability data of the catalyst have not yet been provided. 

Springmarm et ol. [152] simulated a 10-kWei autothermal reformer for gasoline with a one-dimensional, dynamic model. The reformer was a metallic monolith coated with precious metal catalyst. The reformer consisted of two parts both of 70-mm diameter, a small electrically heated monolith only 5-mm long (400 cells per square inch or about 1300-pm channel size) and a second, about 100-mm long monolith (1600 cells per square inch or about 630-pm channel size). Both monoliths were coated with the same catalyst Kinetic data were determined prior to the simulations [56] and heat losses were estimated for the reactors, which is a critical issue. The reformer was operated at a S/C ratio of 2 and an O/C ratio of 0.75. The pressure was 4bar and the feed inlet temperature 500 °C. 

For a methane steam reforming fuel processor, more than 15% higher fuel processor efficiency was determined experimentally by Mathiak et al. [433] when utilising fuel cell anode off-gas compared with combustion of additional methane. Doss et al. analysed an autothermal gasoline fuel processor and found improved efficiency by utilisation of anode off-gas [434].

Present formula gasolines contain approximately 300 ppm. No. 2 fuel oil contains 2,200 to 2,600 ppm by weight of sulfur. Even pipeline gas contains sulfur-containing odorants (mercaptans, disulfides, or commercial odorants) for leak detection. Metal catalysts in the fuel reformer can be susceptible to sulfur poisoning and it is very important that sulfur in the fuel reformate be removed. Some researchers have advised limiting the sulfur content of the fuel in a stream reformer to less than 0.1 ppm, but noted the limit may be higher in an autothermal... 

A compact design for a gasoline fuel processor for auxiliary power unit (APU) applications, including an autothermal reformer followed by WGS and selective oxidation stages, was reported by Severin et al. [83]. The overall fuel processor efficiency was about 77% with a start-up time of 30 min. 

A stand-alone IkW integrated fuel processor for gasoline, incorporating an autothermal reformer followed by high- and low-temperature WGS reactors, was reported by Qi et al. [85]. The start-up of the ATR reformer lasted less than 5 min and stabilized in around 50 min for the whole system.
