Ethanol Steam Reforming Followed by Water‐Gas Shift Reaction over Ce‐Ni/MCM‐41 and Fe‐Based Catalysts

Abstract

AbstractCurrent research focuses on hydrogen production from ethanol steam reforming (ESR) followed by water‐gas shift (WGS) reaction. Ce‐Ni/MCM‐41 and Fe/Ce/M (where M = K, La, Ti) catalysts were prepared by the wet‐impregnation technique and used for the ESR and WGS reactions, respectively. All experiments were carried out at 600 °C. The effects of the reduction time, the ratio of the two catalysts, and their arrangement were also investigated. The best results were obtained using Fe/Ce/Ti as WGS catalyst and with a separate array because the H2 production and CO2 level in the product gas were improved while that of CO was reduced. To generate high‐purity hydrogen, the CaO‐based adsorbent was used as a third layer to adsorb CO2 from the gaseous products.
