Fig. 4: Catalytic activity of Ni/ZrO2 and comparison with literature.
From: A membrane Sabatier system for water recovery and rocket propellant production
a Catalytic activity evaluation of Ni/ZrO2 with H2O vapor permseletive membrane at various GHSVs (T = 300 °C and P = 1.15 bar). b Comparisons of catalytic results in this work with the performance of both reported membrane Sabatier reactors and traditional reactors from literature in terms of CO2 conversion and CH4 space-time yield (Supplementary Table 11). The performance of reported traditional reactors is represented by other symbols (Nos. 1–69). The performance of reported membrane Sabatier reactors is represented by blue stars (Nos. 70–76). The catalytic performance of this work under different gas hourly space velocities and temperatures is represented by red stars (Nos. 77–85).
