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. sugarcane) and the evaluation of the value added to the application of biochar as a biofuel could provide some advantages and is a viable option for increasing the use of biomass efficiently in the Brazilian energy sector; but little is known about this. This work aims to assess the energy potential and the influence when used N2 and CO2 atmospheres on biochar from sugarcane bagasse (SCB) produced.
