Reaction mechanismThe water gas shift reaction (WGSR) is a moderately exothermic reaction between carbon monoxide and steam to form carbon dioxide and hydrogen. In typical industrial applications, the WGSR is conducted as a two stage process. The high temperature stage, conducted over an iron ...

This review provides a consolidated listing of the various important kinetic expressions published for both the high temperature and the low temperature water gas shift reaction along with the details of the catalysts and the operating conditions at which they have been validated. 展开 关键词: water...
A dual-site reaction mechanism is proposed for Pt based water–gas shift catalysts. The sorption equilibrium parameters are evaluated in detail to validate their physical significance. The values of the van ‘t Hoff parameters for CO and H2 correspond to those for chemisorption on platinum. The ...

Water-gas shift reaction: Finding the mechanistic boundary The mechanism of the water-gas shift reaction is discussed for both copper/zinc oxide/alumina and iron oxide/chromium oxide catalysts. The associative and regenerative mechanisms are presented and the evidence concerning each mechanism i... C...
The kinetics of the water–gas change reaction was evaluated with formulated ruthenium catalysts (Ru 2 wt%/TiO2, Ru 2 wt%/Al2O3) in a fixed bed reacto
The mechanism of the water gas shift reaction on gold and other low temperature catalysts has been widely investigated but little agreement exists. However, it is shown that a single "universal" model is consistent with much of the experimental literature. In this, it is proposed that the ...
