A 1%Ni/SBA-15(P) catalyst was synthesized with a P123-assisted impregnation method, which exhibited high CO2 conversion and stability in the reverse water-gas shift reaction. For catalyst, TEM TPR characterizations demonstrated that highly dispersed NiO particles at about 3 nm strongly interacted SiO2 support. During reaction, higher than 1%Ni/SBA-15 prepared by conventional method without P123...

A study on the use of chemical conversion coating as a preparative technique for foam-based structured catalysts, in water gas shift reaction, is presented. The results showed significant correlation between textural properties structure and preparation technique, highlighting how suitable highly porous structures. In first part paper, performance two catalysts obtained by commercial aluminium ...

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 ...

The presence of specific hydrocarbon gas molecules in various types of water cavities in natural gas hydrates (NGHs) are governed by the relative stabilities of these encapsulated guest molecule-water cavity combinations. Using molecular quantum chemical dispersion-corrected hybrid density functional computations, the interaction (ΔE(host--guest)) and cohesive energies (ΔE(coh)), enthalpies, an...

Multiwalled carbon nanotubes (MWCNTs) on a grid supported cobalt nanocatalyst were grown, by exposing it to combustion gases from ethylene/air rich premixed flames. Ten equivalence ratios (φ) were investigated, as follows: 1.37, 1.44, 1.47, 1.50, 1.55, 1.57, 1.62, 1.75, 1.82, and 1.91. MWCNT growth could be observed for the range of equivalence ratios between 1.45 and 1.75, with the best yield ...

The conversion of carbon sources such as coal and methane into liquid fuels, methanol and alkanes, the latter via the Fisher-Tropsch process, requires careful control of the H2/CO ratio in synthesis gas. 1 The control is achieved in industry by the water-gas shift reaction. (Figure 1). 2 The study of carbon monoxide dehydrogenase (CODH) enzymes is significant to the water gas shift reaction bec...
