Shown in Figure 1 below are the feed equilibrium conditions. Expressed is equilibrium CO conversion and CH4, CO, and CO2 effluent composition conditions as a function of temperature, on a dry basis. Other than water, hydrogen is the only other product component and its effluent composition is not shown. The significant temperature influence on product slate can be seen in Figure 1. At 450℃ the CH4 equilibrium composition and CO conversion are 61.6% and 92.57%, respectively. While at 250℃the CH4 composition and CO conversion are 94.2% and 99.99%, respectively. Thus, in just a 200 oC drop in temperature the desired methane equilibrium output increases 32.6%. Due to enhanced WGS functionality the CO2 output increases from 1.7% to 7.0% when the temperature is increased from 250oC to 450oC. For the lunar ISRU process maximum CH4 effluent concentration is desired. Thus, from a thermodynamic perspective, lower operating temperature is desire
