Oxidative Coupling of Methane to Ethylene Over Sodium Promoted Manganese Oxide
Manganese oxide catalyst promoted with sodium and supported on silica exhibits fairly good activity and selectivity towards the synthesis of ethylene from methane at the optimum operating conditions. Methane and oxygen were fed into a tubular fixed bed reactor packed with catalyst under atmospheric pressure. The effects of temperature, residence time and feed composition on conversion, selectiv...
متن کاملCarbon 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 ...
متن کاملKinetic studies of oxidative coupling of methane on samarium oxide
Kinetic behaviour of three samples of samarium oxide (cubic (Sm-1 ), monoclinic (Sm-3) and mixed cubic-monoclinic (Sm 2) ) were studied in the oxidative coupling of methane using a gradientless flow circulation system. The specific rate of C2product formation differed by a factor of 6-8 for Sm-1 and Sm-3. The specific activity for CO formation did not depend upon the crystal structure of samari...
متن کاملNon-oxidative conversion of methane to aromatics over modified zeolite catalysts by transitional metals
The activity of different transitional metals over modified H-ZSM-5 catalysts for methane conversion to aromatics was compared. The first group of catalysts was Mo-impregnated H-ZSM-5 zeolites with 1, 3 and 6 wt% of Mo. The second group was M(3 wt%)- impregnated H-ZSM-5 (M: Ag, Cd, Cr, Mo, Zn and Mn). The catalytic activity of the first group was investigated at 600, 700 and 800 °C and gas hour...
متن کاملOxidative coupling of methane over doped Li/MgO catalysts
A series of zirconia doped Li/MgO catalysts with a fixed amount of zirconia and varying concentrations of lithium was used for the oxidative coupling of methane. It was found that an increase in lithium concentration resulted in a decrease in initial activity, while the selectivity was not affected. The life-time of Zr doped Li/MgO catalysts with a fixed concentration of ZrOz is a function of t...
