A comparison study on high-temperature water–gas shift reaction over Fe/Al/Cu and Fe/Al/Ni catalysts using simulated waste-derived synthesis gas

Hydrogen production from water–gas shift reaction over Ni–Cu–CeO 2 oxide catalyst: The effect of preparation methods

“…In addition, CO 2 and H 2 present in the feed gas can lead to the reverse WGS reaction. Traditionally, in order to achieve high reaction rate and a high CO conversion, WGS reaction was performed in two stages with different temperature regions: high temperature wateregas shift (HTeWGS; 350e500 C) using FeeCreO and low temperature wateregas shift (LTÀWGS; 190e250 C) using CueZneAleO catalysts [10,11].…”

The effect of preparation method on Fe/Al/Cu oxide-based catalyst performance for high temperature water gas shift reaction using simulated waste-derived synthesis gas

“…Small crystallite size is associated with high activity as well as high thermal stability in WGS [20]. The high CO conversion of the FAC-CP catalyst is ascribed to the highest BET surface area and the smallest crystallite size.…”

“…Our developed Fe/Al/Cu catalyst exhibited higher catalytic activity and stability than the commercial FeeCr catalyst. However, the high CO concentration of the waste-derived synthesis gas can deteriorate the catalytic performance of commercial FeeCr catalyst because it makes severe conditions [20]. We also reported that a Fe/Al/Cu catalyst prepared by the simple solegel method showed high catalytic performance without an activation procedure [9].…”

“…In addition, using a Cu promoter can enhance the HT-WGS activity of the FeeAl catalyst [17]. Therefore, Fe/Al/Cu catalysts have attracted a great deal of interest due to their outstanding performance for HT-WGS [9,17,20].…”

Hydrogen production by high temperature water gas shift reaction over highly active and stable chromium free Fe–Al–Ni catalysts

“…In addition, the effects of ThO 2 , MnO 2 , MgO and Al 2 O 3 on the catalytic performance of iron based water gas shift catalyst were investigated and the results revealed that Al 2 O 3 could improve the catalyst stability in high temperature water gas shift reaction [12e14]. Jeong et al compared the catalytic activity of FeeAleCu and FeeAleNi catalysts using simulated wastederived synthesis gas and found that FeeAleCu has higher activity than FeeAleNi catalyst [15].…”
