Abstract

A comparative study between monometallic (Me-CeO₂, Me = Zn, Cu, Fe and Co) and Ni-doped bimetallic (Me-Ni-CeO₂) catalysts has been performed in the high temperature water-gas shift (HT-WGS) reaction using waste derived synthesis gas. Experimental results revealed that Me-Ni-CeO₂ exhibited higher catalytic performance than simple Me-CeO₂ catalysts. Within the Me-Ni-CeO₂ series, Co-Ni-CeO₂ exhibited excellent and stable catalytic performance (CO conversion > 90%) at a very high GHSV of 143,000 h^-1. The existence of high concentration of Ce³⁺ ions and oxygen vacancies on the catalyst surface were responsible for the increased WGS activity of Co-Ni-CeO₂. In addition, Co-Ni-CeO₂ maintains a stable performance for 50 h. However, commercial Fe₂O₃-Cr₂O₃ catalyst showed a steep decline from their initial CO conversion values 15-10% within 5 h.
