A supported trimetallic nano catalyst and a fixed bed catalytic process have been developed for the conversion of CO2 + H2O (in the form of steam) + 1% H2 to alcohol and propyne The mixture of CO2 +H2O and H2 is passed over Ru:Mn:Ni nano catalyst dispersed on a high surface area antase titanium dioxide catalyst support at 773 K and at atmospheric pressure with the gas space velocity of 6000-700...

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desor...

Research is ongoing at Stanford University on the catalytic decomposition of nitrous oxide as an environmentally friendly monopropellant for propulsion and power applications. Two meso-scale planar monopropellant thrusters have been successfully tested: one made of monolithic silicon carbide utilizing a commercially supplied catalyst, and the other made of Hastelloy-X ® utilizing a rhodium base...

The decomposition of H2O2 by a novel supported g-FeOOH catalyst was performed in a continuous fluidized-bed reactor. This catalyst has been successfully used in the treatment of organic contaminants with H2O2 in our previous work. In this study, we attempted to determine the effects of pH, H2O2 concentration, and catalyst concentration on the decomposition of H2O2. An approach, we regarded this...

A comprehensive 3D coupled mathematical model is developed to study the microwave assisted thermocatalytic decomposition of methane with activated carbon as the catalyst. A simple reaction kinetic model for methane conversion (accounting for catalyst deactivation) is developed from previously published experimental data and coupled with the governing equations for the microwaves, heat transfer,...

For several decades vanadyl pyrophosphate, (VO)2P2O7, has been used commercially as a catalyst for the partial oxidation of n-butane into maleic anhydride (MA) [1]. However due to the moderate specificity to MA production, many research groups still continue to investigate the V-P-O catalyst system with the aim of further improving its overall performance. Now a specialized form of V-P-O cataly...
