"Energy Efficiency of Hydrogen Sulfide Decomposition in a Pulsed Corona" by Morris D. Argyle, Sanil John et al. 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. Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion.

  The decomposition of toluene in a gliding arc discharge (glidarc) was performed and studied. Experimental results indicate that the glidarc technology can effectively decompose toluene molecules and has bright prospects of being applied as an alternative tool to decompose volatile organic compounds. Hydrogen production from hydrogen sulfide decomposition in a non-thermal plasma packed-bed DBD reactor E. Linga Reddy, V.M. Biju, manyam International Journal of Hydrogen Energy, 37(10), p, () Kinetics of the decomposition of hydrogen sulfide in a dielectric barrier discharge reactor.

Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD and COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. Arc discharge decomposition. Generally, when a voltage is applied to two electrodes, an electrical potential is created which tends to move electrons from the positive pole to the negative. This is what causes an electric flow of electrons or electric .

Hamann,2 Suresh S. Muknahallipatna,2 Stanislaw Legowski,2 John F. Ackerman1, and Morris D. Argyle1 (1) Department of Chemical & Petroleum Engineering, (2) Department of Electrical &. Hydrogen sulfide is an extremely toxic gas which is generated from both nature factors and human factors. A proper method for the efficient decomposition of hydrogen is of great importance.

Using traditional Claus process, hydrogen sulfide could be decomposed into hydrogen oxide and sulfur. One drawback of this process is that the energy stored in hydrogen sulfide. The heat of H2O2 decomposition is about B.t.u. per lb-H2O2. H2O2 decomposition into oxygen, water and heat is a concern which is made more significant if the sulfide containing waste also contains volatile hydrocarbons.

At the time of the infrared survey, the air was tested inside of the motor control center (MCC) and showed the H 2 S gas concentration to be at ppm. The presence of H 2 S gas played a significant role in the growth of the silver filaments on the. Optimum voltage, h2s concentration, temperature, and pressure for h2s decomposition are given.

Method for the Decomposition of Hydrogen Sulfide. Authors The concentration of h2s in industrial gas byproducts could be reduced by exposing h2s-containing gas to a silent electrical discharge to effect decomposition of h2s to s and h2.

Hydrogen sulfide is the chemical compound with the formula H 2 is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs.

It is very poisonous, corrosive, and flammable. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly. The decomposition of hydrogen sulfide (H 2 S) has attracted increasing attention because it produces hydrogen from a hazardous waste gas.

However, the thermal equilibrium limitation in the decomposition gives rise to low H 2 S conversion and high energy costs for hydrogen production. In the present work, we demonstrate that alumina-supported CdS and ZnS .columns.

Despite the advances made in these areas, no method of hydrogen sulfide decomposition can be considered commercially feasible today. 0 20 40 60 80 TEMPERATURE, oC PRODUCT GAS COM P OSIT ION (Vo l %) H 2S H 2 S 2 H 2S = H 2 + 1/2 S 2 Figure 1.
