Table 2 Performances of Ni–Fe/Al–Ti and Ni/Al2O3 catalysts
From: Low-temperature methanation of fermentation gas with Ni-based catalysts in a multicomponent system
Catalyst | Specific surface area (m2/g) | Pore size (nm) | Apparent activation energy (KJ/mol) | Temperature for activity initiation (℃) | Temperature for highest activity (℃) | Reaction rates (mol CO2·g Ni−1·h−1) | CO2 conversion (%) | CH4 selectivity (%) |
|---|---|---|---|---|---|---|---|---|
Ni/Al2O3 | 179.7 | 3.8 | 177.5 | 300 | 360 | 0.51 | 71 | 100 |
3Ni–Fe/2Al–Ti | 76.7 | 4.5 | 98.0 | 206 | 254 | 0.38 | 95 | 99 |
