Vapor Phase Dimethyl Carbonate Synthesis from Methyl Nitrite and Carbon Monoxide over Porous Lithium Aluminate Spinel Supported Palladium Catalyst.

Gas-Phase Synthesis of Dimethyl Carbonate from Methanol and Carbon Dioxide Over Co1.5pw12o40 Keggin-Type Heteropolyanion

The reactivity of Co(1.5)PW(12)O(40) in the direct synthesis of dimethyl carbonate (DMC) from CO(2) and CH(3)OH was investigated. The synthesized catalyst has been characterized by means of FTIR, XRD, TG, and DTA and tested in gas phase under atmospheric pressure. The effects of the reaction temperature, time on stream, and methanol weight hourly space velocity (MWHSV) on the conversion and DMC...

Catalytic Synthesis of Methanol from Hydrogen and Carbon Monoxide on a Copper-zinc Oxide Supported Catalyst

Most kinetic studies of methanol synthesis over Cu/ZnO catalysts have been carried out using mixtures of carbon monoxide and hydrogen. But in some cases (1) the synthesis gas has also contained carbon dioxide (2). Power rate laws as well as complicated rate expressions have been proposed over the years. The detailed kinetics of the surface processes is virtually unknown. With the exception, per...

Abatement of Benzyl Alcohol and Methyl Ethyl Ketone (MEK) from Polluted Air Over Nanostructured Mn -Supported Alumina Catalyst

Carbon Nanotubes Synthesis by Chemical Vapor Deposition of Methane over Zn – Fe Mixed Catalysts Supported on Alumina

Carbon nanotubes were synthesized over a series of Zn-containing Fe/alumina catalysts by chemical vapor deposition method at two reaction temperatures of 850 and 950 °C using methane as a carbon source. Catalysts were synthesized by keeping Fe concentration constant and varying Zn concentration to study the effects of Zn. The catalysts were characterized using X – ray powder diffraction and N2 ...
