Biochar is recognized for its potential in mitigating climate change, especially through carbon sequestration and soil improvement. To this end, it is important to use all co-products from pyrolysis in a sustainable and economically viable way. In this study, the conversion of sugarcane bagasse at varying pyrolysis temperatures was investigated using H-1 NMR spectroscopy and Chenomx for liquid fraction analysis. The yield of biochar decreased significantly from 45.3 to 3.5% with a temperature increase of 300 to 1000 degrees C. The morphological analysis revealed that biochar produced at lower temperatures (300 degrees C and 400 degrees C) showed tubular and spongy structures, whereas at higher temperatures (600 degrees C and 800 degrees C), the structures morphed into holes and thinned further, ultimately degrading further at 1000 degrees C. All samples of biochar showed characteristics promising for soil improvement and carbon sequestration (O/C < 0.4). The analysis of liquid fractions revealed that biomethanol reached its highest concentration of 19.28 mM at 800 degrees C, which coincided with the highest production of acetic and lactic acids. Additionally, the highest concentration of acetone was observed at 600 degrees C. These findings highlight the importance of optimizing pyrolysis conditions for enhanced yields of biochar and platform compounds, as well as the potential of the NMR and Chenomx in bioenergy research.
