The enactment of strict laws on reducing pollution and controlling combustion has given rise to the necessity of considering a new approach to energy supply in the future. One such approach is the use of hydrogen as an alternative to fossil fuels. Hydrogen and synthesis gas are typically produced through the partial oxidation of methane in porous media. This process was theoretically simula...

hydrogen peroxide, an oxidizing agent used in surgery for its antiseptic properties, has been associated with life-threatening complications. we report a case of suspected gas embolism following irrigation of a tibial bone cyst with hydrogen peroxide in a five year-old boy under general anesthesia, who died despite resuscitative measures and a long stay in the intensive care unit.

hydrogen was produced by steam reforming of dimethyl ether (dme) using a physical mixture of commercial hzsm-5 zeolite (for dme hydrolyzing) and cu/zno/al2o3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. the experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °c. the effects of feed temperature and gas hourly space velocity (ghsv)...

Thermal plasma reforming offers advantages in hydrocarbon reforming especially in small to medium scale plants and in plants with fast transients. The combination of a thermal plasma reformer operating with partial oxidation with a catalyst bed will be described. Reduced concentrations of CO (1-3% vol) can be achieved, with high hydrogen yields and minimal plasmatron electrical power requiremen...

Hydrogen production has gained increasing attention as a potential energy carrier, which can utilize many forms of renewable energy, such as biomass, wind and direct solar power. It has increased its significance as fossil fuels are being used up at a high rate and energy security is of greater importance to the United States and many other countries. Furthermore, hydrogen production offers the...

Coatings and thin film materials are employed in many different industrial fields for decades, mainly for protective purposes. This large experience provokes that, currently, a wide variety of technologies for both preparation and characterization are available. Particularly, focusing on energy and environmental applications, three main film types can be distinguished: (1) materials with cataly...

In this paper, we have studied the hydrogen adsorption onto CNCs and BNNCs nano-cones using GCMC simulations. The effects of length and cone apex angle on adsorption property have been investigated. Our results show that with increasing the pressure and decreasing the cone length and cone apex angle except for CNC-300˚, the hydrogen adsorption onto the BNNCs and CNCs was increased. It was also ...

This study carried out to investigate the production of hydrogen using the organic fraction of municipal solid waste OFMSW, where the anaerobic digester was depended as a method for disposing and treating OFMSW and producing bio-hydrogen. Bio-hydrogen production had been studied under different parameters including pH, solid content T.S%, temperature and mixing ratios between the thick sludge t...

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...
