Download or read book Decomposition of Hydrogen Sulfide and Methane in Pulsed Corona Discharge Reactors written by Sanil John and published by . This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas typically contains 70-90% methane (CH4) and 0-5% hydrogen sulfide (H2S). The conversion of CH4 to hydrogen and more valuable unsaturated higher hydrocarbons is of great importance to the petrochemical industry. Direct decomposition of H2S to yield hydrogen and sulfur would be more beneficial than the conventional Claus process which converts H2S into sulfur and water. CH4 and H2S have been separately decomposed in our experiments with a wire-in-tube pulsed corona discharge reactor. The pulsed corona discharge is a good source for generating chemically active species at room temperature, which initiate chemical reactions leading to CH4 and H2S conversion. The effect of capacitance, cathode material, gas flow rate, and specific energy input on conversion, energy efficiency, and product selectivity in the CH4 decomposition process was studied. Ethane and acetylene appear to be formed from dimerization of CH3 radicals and CH radicals, respectively, while ethylene is formed mainly from the dehydrogenation of ethane. Platinum coated stainless steel cathodes slightly enhance CH4 conversion relative to stainless steel cathodes, perhaps due to a weak catalytic effect. As specific energy input increases, energy efficiency for CH4 conversion goes through a minimum, while the selectivity of acetylene has a maximum value. Comparison of CH4 conversion for different types of plasma reactors shows that the pulsed corona discharge reactors may provide an attractive alternative method for low temperature CH4 conversion. H2S was diluted with one of the four balance gases (Ar, He, N2 and H2) to initiate a corona discharge in our reactor. Breakdown voltages are proportional to the partial pressure of H2S and balance gas. H2S conversion rates and energy efficiencies depend on the balance gas and inlet H2S concentrations. H2S conversion in atomic balance gases like Ar and He is more efficient than that in diatomic balance gases like N2 and H2. H2S decomposition in a novel pulsed corona wire-in-tube reactor with quartz view-ports allowed visual observation of the effect of charge voltage and gas composition on the corona distribution. The H2S conversion and energy efficiency of H2S decomposition varied at constant power due to the selected values of the electrical parameters of pulse forming capacitance, charge voltage, and pulse frequency. Low pulse forming capacitance, low charge voltage, and high pulse frequency operation produce the highest energy efficiency for H2S conversion at constant power. H2S conversion is more efficient in Ar-N2 gas mixture than in Ar or N2. These results can be explained by corona discharge observations, the electron attachment reactions of H2S at the streamer energies and the proposed reaction mechanism of H2S dissociation. The lowest energy consumption for H2S decomposition in a plasma reactor at non-vacuum pressures was obtained in an equimolar mixture of Ar and N2 at the lowest value of pulse forming capacitance. The results reveal the potential for energy efficient H2S decomposition in pulsed corona discharge reactors.

This book was released on 2013-06-29 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid rain, global warming, ozone depletion, and smog are preeminent environmental problems facing the world today. Non-thermal plasma techniques offer an innovative approach to the solution of some of these problems. There are many types of non-thermal plasma devices that have been developed for environmental applications. The potential of these devices for the destruction of pollutants or toxic molecules has already been demonstrated in many contexts, such as nitrogen oxides (NOX) and sulfur dioxide (SO2) in flue gases, heavy metals and volatile organic compounds (VOCs) in industrial effluents, and chemical agents such as nerve gases. This book contains a comprehensive account of the latest developments in non-thermal plasma devices and their applications to the disposal of a wide variety of gaseous pollutants.

Available in PDF, EPUB and Kindle. Book excerpt: Recently interest has arisen in the use of electrical discharges to effect chemical reactions. Various types of discharges enable us to alter the conditions of a process over a wide range, and often ro combine the high electron "temperatures" necessary to activ ate certainreactions with the low molecular temperatures of the medium used. This makes it possible to simplify the techniques and apparatus required for a process, and to "quench" the products, thus preventing them from decomposing again. Same work on the use of electrical discharges has already found practical applications, These include the preparation of oxides of nitrogen, hydrocyanic acid, ozone, and hydrogen peroxide, thickening of oils, synthesis of acetylene and its homologs, hydrogenation and dehydrogenation of various oils and animal fats, etc, In the heavy organic-synthesis industry, lower olefins and acetylenes are used an a !arge scale as raw ma terials for producing many valuable products, Methods of producing ethylene, propylene, and butylenes from gaseous and liquid hydrocarbon feedstocks have been widely adopted. However, the production of acetylene which is an important and sometimes indispensable initial product-is mainly based an calcium carbide. De spite a number of recent improvements, this method of acetylene production suffers from high electric power consumption and expensive raw materials, requires several stages, and produces !arge amounts of waste products. V arious lines are being followed in the attempt to find new, more sophisticated means of producing acetylene.
