Effect of ionic strength on GAMS

The catalysts were observed to lead to different molar H2/CO ratios (0.73–0.82) in the outlet stream. According to Bradford et al. [2] and Liu et al. [34], the product H2/CO ratio depends on differences in the CH4 and CO2 conversions by the catalyst. The different conversion rates for these reactants are also related to the RWGS reaction (CO2 + H2 ↔ CO + H2O) as outlined below section.
In order to survey the A769662 state and degree of dispersion of each Ni catalyst, an XPS analysis was performed. The Ni 2p spectra of catalysts after the activity test are provided in Fig. 4, while the Ni/support atomic ratio and oxidation state (Ni/NiO ratio) at the Ni site are shown in Table 2.
