Abstract
Biomass has a low energy density and its direct use in conventional combustion systems faces major challenges. To increase the energy density, recent studies suggest the torrefaction of biomass as a simple, inexpensive and easy to implement process; possessing great potential for its industrial insertion. Torrefied biomass (biochar) is not only cheap and environmentally friendly, but also, it is the only biofuel that could be burned directly in conventional combustion systems. However, there is a lack of technical information on the quality of biochar as an alternative biofuel. This lack of knowledge can lead to the production of biochar not suitable for burning, increasing problems related to the production of slag and scale and reducing combustion efficiency. In Brazil, there are three lignocellulosic biomasses relevant to the energy sector (i.e. sugar cane, sweet sorghum and sorghum biomass) and the evaluation of the value added to the application of biochar as biofuel could provide some advantages and is a viable option for increase the use of biomass efficiently in the Brazilian energy sector; but little is known about this. The work aims to assess the potential of various bio-fuels as biofuels. Biochars will be produced from sugarcane bagasse (SCB), sweet sorghum bagasse (SSB) and sorghum biomass bagasse (BSB) by torrefaction processes. This work brings technical information relevant to future studies on the use of biomass in combustion and oxy-combustion processes.
