Effect 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 کاملMiniplant-Scale Analysis of Oxidative Coupling of Methane Process
For more than three decades, Oxidative Coupling of Methane (OCM) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. Developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...
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...
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...
