Fe0.66Mn1.33SiO3 provided higher conversion of natural gas as compared to FeMnSiO3 and the fuel conversion increased with temperature for both materials.
The fuel conversion increased with temperature for both materials and full conversion was reached above 800 °C with a fuel reactor inventory of 225 kg/MW for Fe0.66Mn1.33SiO3, while FeMnSiO3 was incapable of providing full conversion.
Similar to Figs. 4 and 5 shows the effect of operating pressure on key parameters such as reactors temperature, fuel conversion and carbon dioxide purity in fuel reactor exhaust is shown when SBC is used as a fuel.
a For MC. b For SBC. Figure 4 shows the effect of simulated operating pressure on key parameters such as reactors temperature, fuel conversion and carbon dioxide purity in the fuel reactor exhaust when MC is used as a fuel.
The hydrogen storage capacity was as high as 3.5 wt% for 19 wt% SBH solution at 90% fuel conversion and an operation temperature of 60 °C.
Over 200% enhancement in reactor throughput was achieved with the integrated reactor at 99% fuel conversion with constant reaction temperature profiles over a wide range of fuel flow rates.
The reactor performance was quantified with several metrics including the fuel conversion, hydrogen yield, system temperatures, and preliminary results are shown for short-term catalyst degradation.
This new comprehensive information allowed to highlight systematic deviations between model predictions and experimental measurements, both in some oxygenated species and in fuel conversion at very low temperatures (550 650 K).
The predicted temperature profiles, fuel conversion, relative humidity and pressure drops match experimental data reasonably well.
Motivated by the need for small scale distributed hydrogen generation and lack of detailed modeling tools to aid in reformation system design, two fully coupled models were developed to extend the current understanding of reformation processes as it relates to temperature and fuel conversion, two critical design criteria.
