Book Description
Direct Methane to Methanol: Foundations and Prospects of the Process offers a state-of-the-art account of one of the most interesting and potentially commercial technologies for direct conversion of natural gas into valuable chemicals. The book thoroughly explains the complex and unusual chemistry of the process, as well as possible applications for direct methane to methanol (DMTM). It covers topics involving thermokinetics, pressure, direct oxidation of heavier alkanes, and more, and provides detailed appendices with experimental data and product yields. This book provides all those who work in the field of gas processing and gas chemistry with the theory and experimental data to develop and apply new processes based on direct oxidation of natural gas. All those who deal with oil and natural gas production and processing will learn about this promising technology for the conversion of gas into more valuable chemicals. - Reviews more than 350 publications on high-pressure, low-temperature oxidation of methane and other gas phase hydrocarbons - Contains rare material available for the first time in English - Explains the reasons of previous failure and outlines the way forward for commercial development of the conversion technology - Presents a deep theoretical knowledge of this complex conversion process

Book Description
Experimental results were compared to the model predictions. The overall trend of methane and oxygen conversions as well as product selectivities was shown to be well represented by the kinetic model. It is suggested that methane can be activated by Oz or NO2 at the very beginning of the reaction, while further conversion may then proceed when other potential active radicals (0, H, OH, CH30, etc.) are produced in sufficient numbers. Also it is suggested that conversion through CH30 radical could be the major route for methanol production, while formaldehyde is produced via the CH2OH route. The production of C2H6, results from the coupling of CH3 radicals. Carbon oxides are considered to be produced via HCO radical. The experimental and modelling results were used to consider practical implication. It is concluded that the conversion is not thermodynamically favoured and needs to be controlled by chemical kinetics. Methane conversion is increased by temperature, pressures, residence times and nitric oxide addition, while decreased by increasing CH4/02 ratio. Methanol selectivity is enhanced by increasing pressure, CH4/02 ratio, and nitric oxide addition at low pressures, while there is an optimum temperature and residence time for maximum methanol production.

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.
