Inorganic Complex Precursor: Preparation of Cu-Mn/SiO2 Mixed Oxide Nanocatalyst for Low-Temperature Water-Gas Shift Reaction
The present study examined the effect of three methods of preparation on the properties and catalytic performance of Cu-Mn/SiO2 catalysts for the water gas shift reaction (WGSR). Impregnation and coprecipitation and the new approach of thermal decomposition of [Cu(H2O)6][Mn(dipic)2].2H2O/SiO2 inorganic precursor complex were used for the synthesis of the silica-supported copper-manganese mixed ...
متن کاملLow-temperature water-gas shift reaction over Cu- and Ni-loaded cerium oxide catalysts
In this paper we report on the activity of Cuand Ni-containing cerium oxide catalysts for low-temperature water-gas shift (WGS). Bulk catalysts were prepared in nanocrystalline form by the urea co-precipitation–gelation method. Lanthanum dopant (10 at.%) was used as a structural stabilizer of ceria, while the content of Cu or Ni was in the range of 5–15 at.% (2–8 wt.%). At low metal loadings, C...
متن کاملHigh Temperature Water Gas Shift Reaction over Nanocrystalline Copper Codoped-Modified Ferrites
Iron-containing spinels, also known as ferrospinels, are widely used catalysts for the water gas shift (WGS) reaction. The catalytic activity of spinels containing transition metal ions as dopants or modifiers is influenced by the acid base and redox properties of these ions as well as by their site occupancy amongst the octahedral and tetrahedral sites in the spinel structure. It has been esta...
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 کاملActive Sites and Mechanism for the Water-Gas Shift Reaction on Metal and Metal/Oxide Catalysts
Current industrial catalysts for the water-gas shift reaction are commonly mixtures of Fe-Cr and Zn-Al-Cu oxides, used at temperatures between 350-500oC and 180250oC, respectively. These oxide catalysts are pyrophoric and normally require lengthy and complex activation steps before usage. Improved catalysts are being sought, particularly for lower temperature (e.g., at T<150oC, equilibrium lowe...
