Catalytic conversion of methane and ethylene to propylene
Article Abstract:
Several catalysts have successfully facilitated the conversion of methane and ethylene to propylene in the presence of oxygen. Some of these are lithium chloride and sodium chloride and magnesium oxide. Isotopic labeling experiments were performed to examine the role of methane in the development of the propylene product. Analyses using a kinetic model suggest that the methylation reaction occurred in the surface of the catalyst and not in the gas-phase. Variations in the stability of the vinyl and allyl radicals defined the conversion reaction of methane and ethylene to propylene.

Destructive adsorption of carbon tetrachloride on alkaline earth metal oxides
Article Abstract:
The destructive adsorption of carbon tetrachloride on alkaline earth metal oxides was examined using various spectroscopy techniques. The alkaline earth metal oxides used are MgO, CaO, SrO and BaO. Results showed that the destructive adsorption of carbon tetrachloride parallels the ionicity/basicity of the alkaline metal oxide. BaO and SrO were found to be most active materials. CO2 was only the gas-phase product formed at 200-300 degrees centigrade. Moreover, M4OCl6 was formed at 600 degrees centigrade.
