- Issues of management of the organic fraction of municipal solid waste (biogas production in landfills, leachates with high concentrations of organics, odour problems). - Porribility of energy production from this fraction ...

High rate ponds are wastewater treatment systems that combine heterotrophic bacteria and microalgae communities in a symbiosis relation, which triggers a series of reactions that eliminates pollutants from the water. ...

In the experimental part of the work several catalysts are tested, in order to determine the best candidate among them to produce methane from the reaction between carbon dioxide and hydrogen. These catalysts are ...

The anaerobic digestion is a well-known technology to treat wastes with a high potential of methane recovery (i.e. manures, slaughterhouse waste, animal by-products waste and other types of organic wastes) even presenting ...

Methane emissions are responsible for at least one-third of the total anthropogenic climate forcing and current estimations expect a significant increase in these emissions in the next decade. Consequently, methane offers ...

Anaerobic digestion promotes simultaneous sludge stabilisation and bioenergy generation. Increasing the net energy production would contribute in reducing the energy demand of sewage treatment plants. Thermophilic digestion ...

Direct methane Solid Oxide Fuel Cells (SOFCs) operated under catalytic partial oxidation (CPOX) conditions are investigated, focusing on the processing of the anode support and the anode deactivation caused by carbon ...

Three hydrotalcites of M2+-Mg-Al were synthesized using the co-precipitation method, where M2+ was Fe2+, Zn2+ and Fe2+ + Zn2+. The hydrotalcites and their calcined form of mixed oxides obtained by their thermal decomposition ...
