Abstract

Simulated waste-derived synthesis gas has been tested for hydrogen production through water gas shift (WGS) reaction in the temperature range of $240^{\circ}C{\sim}400^{\circ}C$ over supported Pt catalysts prepared by an incipient wetness impregnation method. MG30, MgO, $ZrO_2$, $Al_2O_3$ and $CeO_2$ were employed as supports for WGS reaction in this study. 1 wt.% $Pt/CeO_2$ catalyst exhibited the highest CO conversion as well as 100% $CO_2$ selectivity. This is due to easier reducibility of $Pt/CeO_2$ and high oxygen mobility and oxygen storage capacitiy of $CeO_2$. $Pt/CeO_2$ catalyst can be a promising catalyst for WGS reaction from waste-derived synthesis gas.
