Biochar: Production, Characterization and Applications

Energetic vectors produced from the thermochemical conversion of biomass and waste is considered as environmental-friendly energy. The syngas composed of CO and H2 at convenient ratio, could be used for various subsequent uses. However the industrial development is hold back by the production of unwanted by-products: tars and biochar/ash (aromatic hydrocarbons and solid residues respectively) which decrease the global efficiency yield and require very costly treatments. Some recent studies investigated potential applications to use these biochars for catalytic or sorbent applications, such as catalytic tar cracking or pollutants removal [1]. Biochars are cheap candidates and their functionalization is an opportunity …
