- W105133307 abstract "The catalytic synthesis of C2H4 directly from CH4 has been examined in the presence of oxygen for many metal oxides containing alkali metal salts. Addition of alkali halides onto metal oxides depressed the catalytic activities of the host oxides in deep oxidation of CH4, but favorably enhanced the direct synthesis of C2H4 from CH4. Among the catalysts tested, the oxides of Mn and Ni with LiCl produced ethylene with high selectivity (ca. 60%) and yield (ca. 27%). The role of alkali halides for the selective synthesis of C2H4 was examined for LiCl-added NiO. It is speculated that the alkali metals incorporated into host metal oxides may inhibit the active centers for deep oxidation of hydrocarbons. The role of halides is to generate chlorine atoms through the formation of CH3Cl. The chlorine atoms may catalyze dehydrogenation of C2H6 into C2H4 in the gas phase." @default.
