• • The In2Zr1Ox/SAPO-11 catalyst achieved 24% COx conversion and 68% C5−C11 selectivity at 380 °C, 3 MPa, and GHSV of 2400 mL/(min·g), surpassing the ~45% ASF limit for gasoline-range hydrocarbons, which is critical for cost-effective CO2-to-fuel conversion.
• • Co-feeding CO/CO2 at a ratio of 0.5 suppressed CO byproduct formation, enhancing C5−C11 selectivity by 8.0% and 16.0% compared to In2O3/SAPO-11 and ZrO2/SAPO-11, respectively, demonstrating the synergy of In-Zr mixed oxides.
• • The catalyst exhibited high isomerization activity: isoparaffins constituted 32.6% of the gasoline fraction with an iso/normal ratio of 12.3, improving octane number and combustion performance, a key factor for fuel quality.
• • Stability testing over 150 h showed only a slight decline from 24% to 23% COx conversion and from 68% to ~65% C5−C11 selectivity, indicating robust industrial durability for long-term operation.
