Methane and Light Alkane (C2-C4) Conversion Over Metal Fluoride-Metal Oxide Catalyst System in Presehydrogenation of ethane, propane and iso-butane were developed. XRD analysis suggested that, with the addition of metal fluorides to metal oxides, partial substitution of cations and/or anions happened between fluorides and oxides, leading to the formation of new phases ( e.g. LaOF ) and expansion/c

Oxidative Coupling of Methane Over Sulfated SrO/La2O3 Catalystsane makes an excellent gaseous fuel, it is desirable to convert it .-step processes to higher molecular weight products for transportation, storage, and utilization as chemical feedstocks. The desired primary reactions are shown in Equations 1–4, while Equation 5 is also a reaction of interest:

Evidence for the Production of Methyl Radicals on the Na2WO4/SiO2 Catalyst Upon Interaction with Metethyl radicals and one with g = 1.910 for W. were simultaneously appeared in the ESR spectrum collected at 77K after the reaction of methane with the catalyst at 750 .C in the absence of gas-phase oxygen. In conjunction with previously published results of the surface characterizations of the cataly

A Comparative Study of Catalytic Behaviours of Sr-Ti, Sr-Zr, Sr-Sn Perovskites and Corresponding Layed for the oxidative coupling of methane. Much higher C. selectivity and yield (35–41% and 11–15%, respectively) were obtained over layered perovskites under the reaction condition of 1073K, CH./O./N.=2:l:4 and F/W=60000 ml/min. Postreaction characterization by XRD and XPS reveals that the layered p
