Title
The study on the catalytic performance and characterization of perovskite catalyst (La0.9Sr0.1Cr1−2xMnxCoxO3±δ) for high temperature water–gas shift reaction with simulated coal-derived syngas
Abstract

•La0.9Sr0.1Cr1−2xMnxCoxO3±δ (x = 0.1–0.3) catalysts showed high CO conversion of 90%.•La0.9Sr0.1Cr1−2xMnxCoxO3±δ (x = 0.1–0.3) catalysts reached the equilibrium CO conversion over 450 °C.•More active compared to the commercial high-temperature shift catalyst.

La0.9Sr0.1Cr1−2xMnxCoxO3±δ (0.1 ≤ x ≤ 0.4) catalysts were prepared by the sol–gel method and investigated for the production of hydrogen from simulated coal-derived syngas via the water-gas shift reaction in the temperature range 400–650 °C. Catalyst characteristics were evaluated using XRD, BET, SEM–EDS and TPR. The La0.9Sr0.1Cr1−2xMnxCoxO3±δ (x = 0.1–0.3) catalysts shows high CO conversion of 90% at 450 °C compared to the commercial HT–WGS catalyst and maintains high activity at higher than 450 °C. Therefore, the most suitable catalyst for the WGS reaction in simulated coal-derived syngas was found to be La0.9Sr0.1Cr0.8Mn0.1Co0.1O3±δ.
