Water-gas Shift Reaction over Ceria-promoted Pt catalysts
Introduction The fuel processor in which hydrocarbon fuels can be converted into hydrogen has recently attracted much attention as a result of the advancement in the fuel cell technology. In a fuel processor, the water-gas shift (WGS) reaction plays a crucial role in the transformation of CO, a well-known poisonous gas to electrode of fuel cell, into hydrogen through reaction with steam. In WGS...
متن کاملGold–ceria catalysts for low-temperature water-gas shift reaction
Nanostructured Au–ceria is a promising new catalyst for low-temperature water-gas shift (LTS). Preparation, characterization, and catalytic properties of this material are reported in this paper. Gold–ceria was prepared by deposition–precipitation (DP), coprecipitation (CP), and gelation methods. The gold loading was varied between 1 and 8.3 at.%, while lanthanum used as a dopant in ceria, was ...
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 کاملMolybdenum Carbide Supported Platinum Catalysts for Water-Gas Shift: A Theoretical and Experimental Investigation
Introduction Early transition metals carbides are catalytically active in a variety of reactions, such as isomerization reactions, hydrogenation reactions, water-gas shift (WGS), hydrocarbon steam reforming, etc. [1]. Our group recently developed a method to load metal catalysts onto high surface area carbide and nitride supports, and demonstrated that Pt supported on Mo carbide (Mo2C) possesse...
متن کاملActivity and stability of low-content gold–cerium oxide catalysts for the water–gas shift reaction
We report here on the high activity and stability of low-content gold–cerium oxide catalysts for the water–gas shift reaction (WGS). These catalysts are reversible in cyclic reduction–oxidation treatment up to 400 8C, are non-pyrophoric, and are thus potential candidates for application to hydrogen generation for fuel cell power production. Low-content (0.2–0.9 at.%) gold–ceria samples were pre...
