Experimental approach in biogas production from agricultural substrates [articol] : test rig and results

Abstract

Nowadays, the studies involving the use of renewable sources of energy are in a continuous stage of development in regard to different theoretical and experimental ways of approach. In the context of global crisis it is imperative to obtain solutions connected with new ways of capitalization of existing sources (wind, hydro, solar, biomass). Biomass residues are of great potential connected with different used technologies, one of them being biogas production in during the anaerobic fermentation process. Degradation is an important part during the process of obtaining biogas and because of this, the presented study underlines some of the characteristics of two different sorts of vegetal biomass, in regard to their physical and chemical properties and behavior during the anaerobic fermentation process in co fermentation with waste water for a treatment plant. Also in this paper is presented a small scale installation used for testing, which is located at the Mechanical Engineering Faculty, Politehnica University Timisoara. Conclusions will be traced relative to the obtained results in order to determine the possible applications of the produced biogas.
