Resumo: A detailed evaluation of the structure of biochar from slow pyrolysis of elephantgrass during its steam gasification was performed. The effects of surface area andinherent alkali and alkaline earth metal (AAEM) species on the reactivity of thebiochar were investigated. Drastic changes in biochar structure occurred through-out the reaction, especially for low degrees of conversion. The BET surface area ofthe biochar increased significantly until the conversion reached 0.49, and therewas a steep decrease at high degrees of conversion. The biochar showed a highAAEM concentration. The aromaticity of the biochar suggested an ordered car-bon structure that can lower the reaction rate. The high syngas yield makes theprocess attractive for generation of renewable energy.
