The high temperature water-gas shift (HT-WGS) reaction using simulated waste-derived synthesis gas has been carried out at gas hourly space velocity (GHSV) of 50,056 h<sup>-1</sup> over Pt promoted Ce/Cu/γ-Al<sub>2</sub>O<sub>3</sub> catalysts. To investigate the effect of preparation method on Pt promoted Ce/Cu/γ-Al<sub>2</sub>O<sub>3</sub> catalyst for the high temperature water-gas shift reaction using simulated waste-derived synthesis gas, Ce-Pt/Cu/γ-Al<sub>2</sub>O<sub>3</sub>, Ce/Cu-Pt/γ-Al<sub>2</sub>O<sub>3</sub> catalysts were prepared by a sequential impregnation method. Among the prepared catalysts, Ce-Pt/Cu/γ-Al<sub>2</sub>O<sub>3</sub> catalyst showed the highest catalytic performance.

−To investigate the effect of precipitation on physico-chemical and catalytic properties of Cu-Zn-Al catalyst, the pH value and injection rate in the precipitation process were systematically changed, and the water-gas shift reaction was carried out. The Cu-Zn-Al catalyst showed the highest CO conversion when the optimized synthesis parameters (i.e., pH=10-10.5 and injection rate=30ml/min) were employed. This is mainly due to the enhanced physicochemical properties such as a high Brunauer-Emmett-Teller surface area, small crystallite size, high Cu dispersion, and easier reducibility.
