Os Efeitos da Temperatura na Produção de Biogás em Biodigestores

Abstract

The use of Biodigesters for the treatment of residues by anaerobic biodigestion has as advantages the production of biogas and fertilizers, ease of implantation and operational simplicity. The production of biogas through the recycling of organic matter, as well as a solution for waste disposal, has become economically cost-effective. In this work the most common types of biodigesters, the general aspects of anaerobic biodigestion, the kinetic models to obtain the parameters that govern this process are presented, and finally, an analysis of the influence of the temperature in one of these parameters, the maximum specific growth rate, and the impact of temperature variations on the biogas production process was studied. The calculations were made with the aid of Octave software, and the results are presented in a graphic interface, built by the author herself.
