abstract in this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. a chemical kinetic model was developed to understand the reaction better. the modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (p×τ). the β value is trait of the energy cost, whatever this value was leeser indicated better...

This paper proposes a novel wind energy conversion system based on a Five-phase Permanent Magnetic Synchronous Generator (5-PMSG) and a Five to three Matrix Converter (5-3MC). The low cost and volume and also eliminating grid side converter controller are attractive aspects of the proposed topology compared to the conventional with back-to-back converters. The control of active and reactive pow...

Matrix Converter (MC) is a direct energy conversion device with high input power factor. In the Direct Matrix Converter modulation, the Space Vector Modulation (SVM) method by simultaneous control of the input current and output voltage is used. In this method sum of the phase voltages in the central point of load is nonzero, then nonzero Common-Mode Voltage (CMV) in central point is produce...

Solar energy conversion into electricity by photovoltaic modules is now a mature technology. We discuss the need for materials and device developments using conventional silicon and other materials, pointing to the need to use scalable materials and to reduce the energy payback time. Storage of solar energy can be achieved using the energy of light to produce a fuel. We discuss how this can be ...

  Methane conversion to higher hydrocarbons by pulsed glow discharge at the atmospheric pressure was investigated. The energy efficiency up to 10 % was obtained which is higher than any value ever published for nonequilibrium plasma conversion of pure methame. This method has a potential for development and it is expected that the energy efficiency will be improved further if the plasma paramet...
