nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

One hundred and thirty-five soil samples were collected from a depth of 2–2.5 m near oil and gas fields of Tatipaka, Pasarlapudi, Ponnamanda, Kaza and Palakollu areas of Krishna–Godavari Basin, Andhra Pradesh, India and were analysed for light hydrocarbon gases. The adsorbed soil gas analysis showed the presence of moderate to low concentrations of methane (CH4; 2–83 ppb), ethane (C2H6; 1–92 pp...

according to the global fuel crisis, it seems necessary to use alternative fuel instead of gasoline. since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. many efforts have been done in order to replace gasoline with natural gas. one of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

The adsorption and surface diffusion of CO on Pd/W( 110) and Cu/Rh( 100) surfaces have been studied using infrared reflection-absorption spectroscopy (IRA.?). For CO adsorbed on 0.14 ML Pd on W ( I lo), the CO is found to diffuse from Pd to W at approximately 200 K. Likewise, CO adsorbed on ~0.1 ML Cu on Rh( 100) will diffuse from the Cu to the Rh at approximately 250 K. In addition, the CO ads...

Mercaptosuccinic acid protected gold nanoparticles (Au@MSA) self assemble to form superlattice (SL) crystals at the air-water interface. These have been used for gas adsorption. The current-voltage (I-V) characteristics of the SL film with embedded SL crystals, obtained by four probe measurements, show Ohmic conduction. The conductance observed was proportional to the polarizability of the adso...

A procedure for determining the structure of vapour and gas adsorbates that is based on the Zeta adsorption isotherm is reported. For vapours and for gases, this isotherm supposes that an adsorbate consists of particle clusters with the number of particles in a cluster denoted ζ, where ζ can be 1, 2, 3… up to a maximum of ζm, and predicts the isotherm constants are independent of pressure. For ...

natural gas is one of the hydrocarbon resources which is consumed vastly in the world. the asian and european markets, facing with a growing demand of hydrocarbon resources especially natural gas, are the most important consuming markets. hence, the security of natural gas supply is very important. based on the estimation of gas supply security index (gssi), the amount of vulnerability of selec...

One of the strategic goals of the modern automobile manufacturing industry is to replace gasoline and diesel with alternative fuels such as natural gas. In this report, we elucidate the desired characteristics of an optimal adsorbent for gas storage. The U.S. Department of Energy has outlined several requirements that adsorbents must fulfill for natural gas to become economically viable, with a...
