Summary: Different feedstocks and different pyrolysis processes produce carbonized materials (biochar) with different properties. The properties of these materials are very important when considering their agricultural uses. The technique of 13C Nuclear Magnetic Resonance (13C-NMR) is a very powerful tool for the characterization of the complex products, especially when aided by multivariate statistics, such as Principal Component Analysis (PCA). In this work, a series of feedstocks, embracing agro-industrial residues (sugarcane straw, orange bagasse, grass straw, soybeans, castor oil and Jatropha cake), urban residues (sewage sludges) and industrial residues (blended refuse) were submitted to two different fast pyrolysis processes, said processes 1 and 2.
