The production of syngas from the pyrolysis-catalytic reforming processed municipal solid waste in form refuse derived fuel has been investigated experimentally using a two-stage fixed bed reactor with 10 wt% Ni–Al2O3 catalyst. gases used were combination steam and carbon dioxide (dry reforming). main focus research was to manipulate H2:CO ratio for targeted end-use applications by optimizing p...

High-power-density alcohol fuel cells can relieve many of the daunting challenges facing a hydrogen energy economy. Here, such fuel cells are achieved using CsH2PO4 as the electrolyte and integrating into the anode chamber a Cu-ZnO/Al2O3 methanol steam-reforming catalyst. The temperature of operation, 250°C, is matched both to the optimal value for fuel cell power output and for reforming. Peak...

An interesting application of agricultural renewable sources is the employment of ethanol for supplying Molten Carbonate Fuel Cells (MCFCs). For that purpose, ethanol has to be converted into hydrogen by a steam reforming process. MCFCs are particularly suitable for this kind of applications due to their high tolerability to the impurities which are contained into the reaction products and also...

Energy-efficient CH4-CO2 valorization to fuels and chemicals presents an urgent need considering the great variety of methane sources removal greenhouse gases. In present work, microwave-assisted dry reforming methane, DRM, has been carried out in a custom-designed rectangular mono-mode microwave applicator over several catalyst-support combinations, i.e., Pt/C, Ni/Al2O3, mechanical mixture Ni/...

Three conventional and novel hydrogen and liquid fuel production schemes, i.e. steam methane reforming (SMR), solar SMR, and hybrid solar-redox processes are investigated in the current study. H2 (and liquid fuel) productivity, energy conversion efficiency, and associated CO2 emissions are evaluated based on a consistent set of process conditions and assumptions. The conventional SMR is estimat...

This work is part of the VABHYOGAZ (valorization biogas into hydrogen) program, which targeted industrial deployment hydrogen production from in France. To-date, different processes methane reforming, such as steam reforming (SRM), dry (DRM) and tri-reforming (TRM), have been studied literature, but only SRM applied at scale. Since an energy-intensive process, a critical analysis these routes f...

Hindgut is a major colonization site for Escherichia coli O157 in cattle. In this study, diets were formulated to effect changes in hindgut fermentation to test our hypothesis that changes in the hindgut ecosystem could have an impact on fecal shedding of E. coli O157. Feedlot heifers (n = 347) were prescreened for the prevalence of E. coli O157 by fecal and rectoanal mucosal swab cultures. A s...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...
