This book was released on 2006 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Kinetic rates pertinent to electron loss mechanisms within a non-self-sustained plasma are investigated. In an oxygen containing plasma the examined mechanism is three-body electron attachment to O2. When oxygen is absent from the gas, the dominant electron loss mechanism is electron-ion recombination. The equilibrium rate coefficients for three-body electron attachment to O2 are determined for the species-specific third body collision partner in an N2/O2 gas mixture at 300 K. These rate coefficients are compared to literature values and are found to be on the same order of magnitude but a factor of 2-4 larger. A state of vibrational nonequilibrium is then imposed upon the system wherein the vibrational level populations, which are highly non-Boltzmann, are characterized by a vibrational temperature (>2000 K) which is nearly an order of magnitude greater than the translational/rotational temperature (~350 K). It is demonstrated that the vibrational excitation activates the O2− electron detachment pathway, completely mitigating three-body electron attachment to O2. Lastly, a kinetic model is used to compare energy transfer rates in an RF coupled, laser sustained N2/CO molecular plasma. The plasma is generated and maintained by a cw CO gas laser that causes associative ionization of CO. An RF field coupled to the plasma increases the average electron energy of the system, reducing the electron-ion recombination rate. It is shown that while the rates used predict the vibrational level populations with reasonable accuracy, the agreement is not as good between the predicted and observed translational temperatures of the system.

Available in PDF, EPUB and Kindle. Book excerpt: Providing a fundamental introduction to all aspects of modern plasma chemistry, this book describes mechanisms and kinetics of chemical processes in plasma, plasma statistics, thermodynamics, fluid mechanics and electrodynamics, as well as all major electric discharges applied in plasma chemistry. Fridman considers most of the major applications of plasma chemistry, from electronics to thermal coatings, from treatment of polymers to fuel conversion and hydrogen production and from plasma metallurgy to plasma medicine. It is helpful to engineers, scientists and students interested in plasma physics, plasma chemistry, plasma engineering and combustion, as well as chemical physics, lasers, energy systems and environmental control. The book contains an extensive database on plasma kinetics and thermodynamics and numerical formulas for practical calculations related to specific plasma-chemical processes and applications. Problems and concept questions are provided, helpful in courses related to plasma, lasers, combustion, chemical kinetics, statistics and thermodynamics, and high-temperature and high-energy fluid mechanics.
Download or read book Methane Conversion written by D.M. Bibby and published by Elsevier. This book was released on 1988-03-01 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume comprises the invited plenary lectures, contributed and poster papers presented at a symposium organised to mark the successful inauguration of the world's first commercial plant for production of gasoline from natural gas, based on the Mobil methanol-to-gasoline process. The objectives of the Symposium were to present both fundamental research and engineering aspects of the development and commercialization of gas-to-gasoline processes. These include steam reforming, methanol synthesis and methanol-to-gasoline. Possible alternative processes e.g. MOGD, Fischer-Tropsch synthesis of hydrocarbons, and the direct conversion of methane to higher hydrocarbons were also considered.The papers in this volume provide a valuable and extremely wide-ranging overview of current research into the various options for natural gas conversion, giving a detailed description of the gas-to-gasoline process and plant. Together, they represent a unique combination of fundamental surface chemistry catalyst characterization, reaction chemistry and engineering scale-up and commercialization.
