Conversion of Methane to Higher Hydrocarbons Over Supported Transition Metal Oxide Catalystserable interest has been concentrated on the production of higher hydrocarbons from methane, especially the oxidative coupling of methane to ethylene and ethane.. Although several promising catalysts have been discovered, it is difficult to obtain high activity and high C. hydrocarbons selectivity s

Effects of Product Separation on the Kinetics and Selectivity of Oxidative Couplings been widely investigated. Several reviews of this area have been published (1, 2, 3). A broad range of oxide materials has been studied, including: transition metal oxides (4, 5), alkali-doped, basic oxides such as MgO (6, 7), and rare-earth oxides (8, 9). With all of these materials, deep oxidati

Reactive Vs. Adsorbed Oxygen in the Heterogeneous Oxidation of Methane Over Li / MgOrometry in a lowpressure, continuous flow reactor between 930–1130 K. Under these conditions, which suppress gas-phase reactions, only purely heterogenous processes take place in this system. Dosage of the amounts of bound oxygen removed at several stages of evacuation, or consumed by reaction with

The Role of Free Methyl Radicals in the Selective Oxidation of Methane Over Silica-Supported Molybdeve oxidation to formaldehyde.. The fate of the methyl intermediate, particularly whether it is desorbed into the gas phase and the surface involvement in the subsequent steps is as of yet unresolved. Various scenarios with differing amounts of surface involvement have been proposed. Dowden ... have

Transient Studies of Methane Oxidative Coupling Over Li Promoted LaNiO3 Catalystsotion improves ethane and ethylene selectivity on otherwise completely unselective catalysts. Transient and oxygen isotopic exchange experiments indicate involvement of lattice oxygen in the methane activation process. It is also shown that the presence of lithium significantly lowers a degree to wh
