Book Description
A reasonable case could be made that the scientific interest in catalytic oxidation was the basis for the recognition of the phenomenon of catalysis. Davy, in his attempt in 1817 to understand the science associated with the safety lamp he had invented a few years earlier, undertook a series of studies that led him to make the observation that a jet of gas, primarily methane, would cause a platinum wire to continue to glow even though the flame was extinguished and there was no visible flame. Dobereiner reported in 1823 the results of a similar investigation and observed that spongy platina would cause the ignition of a stream of hydrogen in air. Based on this observation Dobereiner invented the first lighter. His lighter employed hydrogen (generated from zinc and sulfuric acid) which passed over finely divided platinum and which ignited the gas. Thousands of these lighters were used over a number of years. Dobereiner refused to file a patent for his lighter, commenting that "I love science more than money." Davy thought the action of platinum was the result of heat while Dobereiner believed the ~ffect ~as a manifestation of electricity. Faraday became interested in the subject and published a paper on it in 1834; he concluded that the cause for this reaction was similar to other reactions.

Book Description
The conversion of methane to higher hydrocarbons via oxidative coupling over metal oxide catalysts is the subject of intense study as a route for natural gas upgrading. Detailed study on the reaction of methane over a mixed manganese-magnesium oxide implicates a mechanism involving generation of methyl radicals at the surface, followed by radical coupling as well as other radical reactions in the gas phase as the predominant mode of carbon-carbon bond formation. Analysis of the consequences of this mechanisms suggests that there is an inherent limit on yield, including a major adverse pressure effect, that may severely impact the potential utility of this route. Among several possible approaches to circumventing this limitation, a novel class of catalyst - transition metal-exchanged P -alumina -- has been found to be highly active for complete oxidation of methane. Results of catalytic and characterization studies will be presented.
