The steam reforming of hydrocarbon fuels is a promising method for the production of hydrogen for portable electrical power sources. A suitable reactor for this application, however, must be compatible with temperatures above 800 degrees C to avoid coking of the catalytic structures during the reforming process. Here, ceramic microreactors comprising high surface area, tailored macroporous SiC ...

Fuel vapour composition and flammability properties of E85 A series of experiments have been conducted to study the flammability characteristics and determine the flammable temperature range of E85 fuel vapours. E85 is a mixture of ethanol and petrol the composition varies depending on time of the year. According to the Swedish standard, SS 155480:2006, the ethanol content may not be below 70 %...

Practical applications of microbial fuel cells (MFCs) for wastewater treatment will require operation of these systems over a wide range of wastewater temperatures. MFCs at room or higher temperatures (20-35°C) are relatively well studied compared those at lower temperatures. MFC performance was examined here over a temperature range of 4-30°C in terms of startup time needed for reproducible po...

Title of Dissertation: High Temperature Radiation Absorption of Fuel Molecules And An Evaluation of Its Influence on Pool Fire Modeling Kaoru Wakatsuki Doctor of Philosophy, 2005 Dissertation Directed By: Associate Professor, Jungho Kim Associate Professor, Greg Jackson Department of Mechanical Engineering Infrared absorption coefficients of various gas and liquid fuels (propane, nheptane, meth...

Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in m...

Abstract— Porous Hydroxyapatite (HAP, Ca10(PO4)6(OH)2 possessing bioactivity, biocompatibility, solubility and adsorption is highly useful as a biomaterial in various applications . Pure HAP nanoparticles were synthesized at moderate temperatures by wet chemical synthesis and subjecting it to combustion method with a organic fuel ( ascorbic acid). The X-ray diffractometry (XRD) and Fourier tran...

The unresolved Q-branch profiles in the Raman spectra of' nitrogen in premixed, laminar, methane-air, propane-air and butane-air flames with lean to stoichiometric fuel-air equivalence ratios have been recorded experimentally and used to determine flame temperature s with a precision of about 10f0using an iterative computer program which fitted calculated nitrogen spectra to the experimentally ...

Plasmatron reformers are being developed at MIT and ArvinMeritor [1]. In these reformers a special low power electrical discharge is used to promote partial oxidation conversion of hydrocarbon fuels into hydrogen and CO. The partial oxidation reaction of this very fuel rich mixture is difficult to initiate. The plasmatron provides continuous enhanced volume initiation. To minimize electrode ero...
