Abstract
The goal of this study was to investigate the Cs-promoted Ni/Fe catalysts for high temperature shift reaction. The performance of all the catalysts was evaluated at 400 °C and 75,000 ml/gcat h under the reactant composition: 56.7% H2, 10% CO, 26.7% H2O, and 6.7% CO 2, assuming gas production from the steam methane reformer at a H2O/CH4 ratio = 3 with 100% CH4 conversion and with no extra steam added for the protection of the catalyst. The Cs/Ni/Fe (Ni:Fe = 34:66; weight ratio) catalysts of 3.9-6.0 Cs wt.% showed excellent CO removal activities and suppressed the progress of methanation effectively. This performance was related to the increment of amount in weakly basic sites through Cs promotion.
