The study on the catalytic performance and characterization of perovskite catalyst (La0.9Sra1 Cr1 _2xMnxCox03+6) for high temperature water-gas shift reaction with simulated coal-derived syngas
Lam Sro., Cr1 _2xMnx Cox 03+3(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 Lam Sro.i Cri _2xMnx Cox 03+3 (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 Lam Sro.i Cro.8Mno.1 Coo.] 03+s" 2013 Elsevier B.V. All rights reserved.
