Abstract
Pyro-BIOGAS is a project that proposes com- bined waste management applying anaerobic digestion and pyrolysis processes for recove- ring energy. This project aims to encourage the use of renewable resources that are currently considered as waste for energy production. In order to attain the main objectives propo- sed, it was performed an evaluation of biogas production yields of different waste materials, along with the analysis of thermal and kinetic properties during pyrolysis of digested material. With this information, energy efficiency and eco- nomic feasibility of a combined process of anae- robic digestion of swine manure and pyrolysis of the digestate with lignocellulosic material was studied. On the other hand, burning characte- ristics of the gas thus obtained were evaluated. Through the combined use of biogas and pyrolysis gases, self-sufficient systems can be achieved, with extra energy production to be used for other purposes in the installation. It was observed, that burning characteristics, such us flame speed and temperature were affected by H2 and CO2 content.
