📄 Abstract（原文）
Carbon monoxide (CO) in gasification‐derived syngas reduces hydrogen quality and can deactivate downstream catalysts. This study investigates Fe‐based catalysts with varying Cu, Al, and Ti molar ratios for CO removal via the water–gas shift reaction. Catalytic performance was evaluated at 250–300 °C, gas hourly space velocities of 3000–10 000 h −1 , and steam/CO ratios of 1:1–3:1. Among the catalysts studied, Fe 1 Cu 3 Al 10 exhibited the best performance, achieving 96% CO conversion, CO 2 selectivity above 90%, and an H 2 yield of 40.8%. Catalyst characterization using X‐ray diffraction, scanning electron microscopy, N 2 adsorption–desorption, X‐ray photoelectron spectroscopy, H 2 ‐temperature‐programmed reduction, and CO temperature‐programmed desorption revealed that Ti incorporation altered catalyst crystallinity and morphology, whereas Fe 1 Cu 3 Al 10 maintained good structural stability after reaction. Under integrated gasification conditions, Fe 1 Cu 3 Al 10 reduced the CO concentration to 2.1% while increasing the H 2 yield to 41%. These findings identify Fe 1 Cu 3 Al 10 as a promising catalyst for CO removal and hydrogen enrichment in gasification‐derived syngas upgrading systems.
