Available in PDF, EPUB and Kindle. Book excerpt: This project addresses the conversion of methane from natural gas into ethane, ethylene and higher hydrocarbons. Our research explores the mechanistic and practical implications of carrying out the methane oxidative coupling reaction in reactor designs other than conventional packed-beds with co-fed reactants. These alternate reactor designs are needed to prevent the full oxidation of methane, which limits C2, yields in methane oxidative coupling reactions. The research strategy focuses on preventing contact between the 02 reactant required for favorable overall thermodynamics and the C{sub 2+} products of methane coupling. The behavior of various reactor designs are simulated using detailed kinetic transport models. These simulations have suggested that the best way to prevent high C02 yields is to separate the oxygen and hydrocarbon streams altogether. As a result, the project has focused on the experimental demonstration of proton transport membrane reactors for the selective conversion of methane into higher hydrocarbons.

This book was released on 2013 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Equilibrium models were constructed for Oxidative Coupling of Methane reaction (OCM) with three catalysts, i.e. Mn/Na2WO4/SiO2, La2O3/CaO and PbO/Al2O3. The models were verified under operating temperatures of 650-900oC and methane to oxygen feed ratio 3-10. The compositions of methane, ethane, ethylene, hydrogen, water and carbon oxides in the effluent of each model were compared with the corresponding experiments. The suitable equilibrium model for both Mn/Na2WO4/SiO2 and PbO/Al2O3 was the trio-equilibrium reaction model, consisting of OCM and oxidative dehydrogenation model, combustion model, and hydrocracking model. While, the duo-equilibrium reaction model, containing OCM and oxidative dehydrogenation model, and combustion model, was appropriate for La2O3/CaO catalyst. The accuracy of all equilibrium models could be improved by specifying the desired ethane yield. In addition, based on the reactor performance, i.e. conversion, and yields, the limitation of the manipulated equilibrium models was evaluated within the operating temperatures and the methane to oxygen ratio above. Finally, the equilibrium models, especially the duo-equilibrium model, could be employed to predict the reactor performance containing other OCM catalysts.

Book Synopsis Methane Conversion by Oxidative Processes by : Wolf
Download or read book Methane Conversion by Oxidative Processes written by Wolf and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-oxidative methane coupling is the process of converting methane to C2 products through the C-C coupling of two methyl groups. While C2 products such as ethylene and ethane are valuable products as potential chemical feedstocks in the petrochemical industry, the process is limited by low yields of value-added products as the thermodynamic equilibrium favors heavy hydrocarbons and coke products under traditional continuous heating at high temperatures. Platinum has shown to be an appropriate catalyst for dissociating methane and adsorbing methyl groups to eventually form C2 products. Density functional theory (DFT) calculations are used to identify the reaction mechanism over a single platinum atom catalyst adsorbed on In2O3 (111), V2O5 (010), ZnO (100), and Ga2O3 (100) metal oxide supports. Pt/Ga2O3 (100) resulted in the lowest predicted apparent energy barrier to forming ethane as a result of stable intermediates along the reaction pathway. Controlling the time dependence of reactor temperature through dynamic heating profiles can alter the overall reactor performance. The ethylene yield on a FeC2 on SiO2 catalyst was significantly improved to 18% under a controlled heat pulse duration of 10 ms. The distribution of ethylene yield over various pulse durations and temperature ranges provides insight into reactor conditions that can best optimize the production of value-added products in methane conversion.
