Direct methane activation on a mesoporous material under dielectric barrier discharge (DBD) plasma was investigated in the present study. The specific surface area of the mesoporous material (SBA-15) was controlled by varying the hydrothermal reaction temperature to investigate the effect of the specific surface area on the methane activation. As a result, methane conversion increased as the sp...

Plasmatron fuel converters have been investigated for the conversion of a wide range of fuels. This is a paper of a series of papers describing an effort to investigate experimentally and computationally plasmatron methane reformers. This paper describes the fluid dynamics modeling of the plasmatron methane reformer, with the hope of understanding air/methane mixture and mixing rates in the reg...

cobalt chromite (cocr2o4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (ngv). in this study, cocr2o4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. cobalt nitrate hexahydrate, chromium nitrate nonahydrate and ammonia solution (25%) ...

In this paper, recent results of plasma processing of natural gas are described. The use of a plasma reformer for the generation of hydrogen rich gas from natural gas has been investigated. In an accompanying paper, progress in plasma reforming of diesel fuel is described. The reformate composition has been investigated as a function of the initial mixture of air and methane. High methane conve...

The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...

Plasmatron fuel converters have been investigated for the conversion of a wide range of fuels. This paper is a series of papers describing an experimental and computational study of plasmatron methane reformers. This paper presents a model that uses limited mixing and chemical kinetics to investigate the plasma assisted reforming of natural gas. The Partially Stirred Reactor (PaSR) model from t...

the role of nickel as catalyst on the conversion of methane and ethylene in a gas phase flow reactor in the absence of oxygen is studied. in this study, nickel in its different forms is used as catalyst. the role of pressure, flow rate, and temperature on the conversion of feed gases is investigated. the experiments have been carried out in the presence and absence of the catalysts to measure t...

The possibility of converting methane into hydrogen using a high-frequency induction plasma torch at the atmospheric pressure has been experimentally studied. dependencies degree conversion and rate production were studied depending on process conditions. It demonstrated that methane-to-hydrogen can reach values close to 100%. Keywords: plasmolysis, HF torch, hydrogen.
