Deactivation Mechanisms for Pd/Ceria During the Water-Gas Shift Reaction
The mechanism responsible for the irreversible deactivation of ceria-supported precious metals for the watergas-shift reaction has been investigated through accelerated aging tests. It is shown that deactivation of Pd/ ceria occurs more rapidly at 673 K compared to 523 K when operating with an integral reactor in 25 torr each of CO and H2O. By heating a fresh catalyst in H2, H2O, CO, or CO2, it...
متن کاملBioreactor Scale-up for Water-Gas Shift Reaction
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
متن کاملCombined Three Mechanisms Models for Membrane Fouling during Microfiltration
Five new mathematical triple fouling models were developed to explore the flux decline behavior during the microfiltration. The first model was developed by the assumption of the successive effects of standard mechanism, intermediate pore blockage and cake formation by using the standard blocking flux expression in the model calculations. The second and third models also obtained by the success...
متن کاملThe formate and redox mechanisms of water-gas shift reaction on the surface of Ag: A nanocluster model based on DFT study
Two different possible mechanisms of water gas shift reaction including formate and redox mechanisms on the Ag5 cluster were investigated using DFT computations. All the elementary steps involved in both mechanisms were considered. It was observed that dissociation of H2Oads and OHads, as well as formation of CO2(ads), required activation e...
متن کاملDeactivation of a Au/CeO2 catalyst during the low-temperature water–gas shift reaction and its reactivation: A combined TEM, XRD, XPS, DRIFTS, and activity study
The deactivation of Au/CeO2 catalysts during low-temperature water–gas shift reaction and the underlying physical origin were investigated, comparing the deactivation in different reaction atmospheres and subsequent regeneration of the catalysts by reactive treatment in O2/N2 or H2O/N2 gas mixtures. Based on TEM and XRD measurements, Au and ceria particle sintering (irreversible deactivation) c...
