WGS activity of a novel Cu-ZrO2 catalyst prepared by a reflux method. Comparison with a conventional impregnation method
(2013)
The activity in the WGS reaction of Cu/ZrO2 catalysts prepared by a method of refluxing in an aqueous NH4OH solution is studied. It is shown that at 3% Cu load the methods of impregnation over monoclinic or tetragonal ZrO2 ...
Simulation of a membrane reactor for the WGS reaction: Pressure and thermal effects
(Elsevier Science Sa, 2009-11)
A simulation study of a membrane reactor for the water-gas shift reaction is presented. A pseudohomogenous 1D mathematical model is considered to describe the performance of the membrane reactor under steady-state operation. ...
Study of the water-gas shift reaction over Pt supported on CeO2–ZrO2 mixed oxides
(Elsevier Science, 2011-08)
The water gas shift (WGS) reaction was studied on Pt/CeO2, Pt/ZrO2 and Pt/CexZrx-1O2 catalysts. All the samples were characterized by a variety of physical and spectroscopic techniques. The catalysts activities were evaluated ...
Single Ni Sites Supported on CeO 2 (111) Reveal Cooperative Effects in the Water-Gas Shift Reaction
(American Chemical Society, 2019-04)
Density functional theory (DFT) calculations have been performed to study the water-gas shift (WGS) reaction mechanism via the formation of a carboxyl (COOH) intermediate over a low-loaded Ni/CeO 2 (111) model catalyst for ...
Pelletized Cu-Ni/CePr5 catalysts for H2 purification via Water Gas Shift reaction
(Elsevier, 2020-07-01)
Water Gas Shift (WGS) reaction recently gained attraction as a purifying method to remove CO in H2 stream produced from bio-alcohols reforming for fuel cells applications. In previous works, we tested Cu-Ni samples supported ...
Understanding the Role of Oxygen Vacancies in the Water Gas Shift Reaction on Ceria-Supported Platinum Catalysts
(ACS Publications, 2014-06)
Reducible oxides have been shown to greatly improve the activity of water gas shift (WGS) catalysts. The precise mechanism for this effect is a matter of intense debate, but the dissociation of water is generally considered ...
Novel catalyst for the WGS reaction in a Pd-membrane reactor
(Elsevier, 2013-07)
A Pt/La2O3·SiO2catalyst was synthesized and tested in the WGS reaction. Kinetic measurements werecarried out in a conventional fixed-bed reactor operated in differential mode while the stability test wasconducted in integral ...
