Abstract

La_0.9Sr_0.1Cr_1-2xMn_xCo _xO_3±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 La_0.9Sr_0.1Cr _1-2xMn_xCo_xO_3±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 La_0.9Sr_0.1Cr _0.8Mn_0.1Co_0.1O_3±δ.
