Cinética e mecanismo envolvidos na geração de biogás

Abstract

Anaerobic digestion is a complex metabolic process that transforms organic material into carbon dioxide and methane, with small amounts of other gasses, depending on the interaction of different groups of bacteria under anaerobic conditions. The precise synchronization of the mechanisms involved in biogas generation is fundamental to guaranteeing the effectiveness of the system, thus avoiding disturbances that could inactivate the reactor. The kinetics of anaerobic digestion make it possible to identify and quantify the parameters that influence the evolution of this process. Understanding the kinetic parameters is extremely important for carefully evaluating the performance of the process under specific operating conditions, and they can be defined using mathematical models that represent the dynamics of the process within limits established in advance. Thus, the general objective of this dissertation was to carry out a literature review in order to evaluate the factors that influence the mechanism of the anaerobic digestion process and to analyze the kinetic models for certain operating conditions
