Oxidative 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...
متن کاملEffect of Additives on Mn/SiO2 Based Catalysts on Oxidative Coupling of Methane
The Oxidative Coupling of Methane (OCM) over M-Na-Mn/SiO2 catalysts (M=W, Cr, Nb and V) was investigated using a continuous-flow quartz reactor at 775°C, 1 atm and 100 cm3min-1 gas flow rates, and correlated with the observed structure and redox properties.The interaction effects of the metal-metal and metal-support on the...
متن کاملPotassium/calcium/nickel oxide catalysts for oxidative coupling of methane
A series of potassium/calcium/nickel oxides were tested for the oxidative coupling of methane (OCM) at 843-943 K and water addition to the feed at O-65 mol-%. The K/Ni ratios varied from 0.0-0.6 and Ca/Ni from 0.0-11; catalysts with no nickel were also tested. At least 10% water in the feed and temperatures lower than ca. 940 K were necessary to keep nickel-containing catalysts from converting ...
متن کاملComparison of Oxidizing Agents for the Oxidative Coupling of Methane over State-of-the-Art Catalysts
The synthesis of selected state-of-the-art catalysts providing high performances in the oxidative coupling of methane (OCM) with O2 was reproduced according to the respective methods reported in literature. A reference material with identical stochiometric composition was further synthesized by applying the cellulose templating (CT) method. This method increases the surface area and affects the...
متن کاملModeling of Oxidative Coupling of Methane over Mn/Na2WO4/SiO2 Catalyst Using Artificial Neural Network
In this article, the effect of operating conditions, such as temperature, Gas Hourly Space Velocity (GHSV), CH4/O2 ratio and diluents gas (mol% N2) on ethylene production by Oxidative Coupling of Methane (OCM) in a fixed bed reactor at atmospheric pressure was studied over Mn/Na2WO4/SiO2 ca...
