Fe2O3/Y2O3 Catalyst Supported on Alumina and Halloysite

Effect of Catalyst Structure on Oxidative Dehydrogenationof Ethane and Propane on Alumina-Supported Vanadia

The catalytic properties of Al2O3-supported vanadia with a wide range of VOx surface density (1.4-34.2 V/nm) and structure were examined for the oxidative dehydrogenation of ethane and propane. UV-visible and Raman spectra showed that vanadia is dispersed predominately as isolated monovanadate species below ~2.3 V/nm. As surface densities increase, two-dimensional polyvanadates appear (2.3-7.0 ...

Investigation of Activity and Selectivity of n-Heptane by Reforming Pt-Ta Catalyst Supported on y-Alumina

The catalyst Pt-Ta supported on 7-alumina was prepared by impregnation with solution containing compoundsof II21K1.0. and Ta205 The Pt concentration was kept constant at 0.2 vet% while the concentration of thetantalum was 0,4 wt%. The activity and selectivity of catalyst were determined under conditions at 450-500 °Cand 15-30 atm.. with molar ratio H2/C[H,e5 and WH=1.5mL/h for converted n-hepta...

Alumina supported molybdenum catalyst for lignin valorization: Effect of reduction temperature.

Alumina supported molybdenum catalysts were prepared with an impregnation method. The activity of the catalyst in the ethanolysis of Kraft lignin to C6-C11 molecules, i.e. alcohols, esters, monophenols, benzyl alcohols and arenes, was tested in a batch reactor at 280 °C with initial 0 MPa nitrogen. The complete conversion of lignin to small molecular chemicals was achieved without the formation...

A Novel Method for Preparation of Alumina-Supported Rhenium-Cesium Catalyst, Re-Cs/-Al2O3

Alumina-supported Cs3[Re(C2O4)3] precursor has been synthesized  for preparation of Re-Cs/g-Al2O3 catalyst. Cs3[Re(C2O4)3]  has been prepared from the reaction of ReCl3 with  H2C2O4.2H2O and CsCl in ...
