Model for biomass gasification including tar formation and evolution (2013)
Journal Article
Palma, C. F. (2013). Model for biomass gasification including tar formation and evolution. Energy and Fuels, 27(5), 2693-2702. https://doi.org/10.1021/ef4004297

Since tar elimination from the product gas is necessary to make gasification an attractive option, the presence of tar was included in a kinetic model. Lignin was assumed as the main precursor of tars due to its aromatic nature; therefore, the lignin... Read More about Model for biomass gasification including tar formation and evolution.
