BIOGAS AS AN ENERGY SOURCE FOR INTERNAL COMBUSTION ENGINES: A REVIEW

Resumo

Biogas has risen, as a renewable technology promising to convert litter organic substance into energy; among its components, in terms of energy, methane is the most important chemical component, particularly for the combustion process in vehicular engines. The use of methane derived from landfill organic matter waste to replace fossil fuel minimizes environmental impact by providing a significant reduction in greenhouse gas emissions. This paper reviews the environmental, social and economic aspects of biogas as a source of energy, the process of producing this renewable energy, and the potential of biogas in producing energy for internal combustion engines. Studies have shown that biogas is a driver for sustainable regional and local development, since energy consumers themselves, becoming producers, can product biogas  and be better able to control inputs for their production activities. For engine applications, it has been found that by adding a certain proportion of H₂ to biogas, the combustion properties can be improved.
