“…From the information provided by this graph, it was observed that formic acid is the chemical product with the highest formation from sugarcane bagasse under HTC conditions, followed by levulinic acid. According to what has been reported by other studies, cellulose and hemicellulose in a hydrothermal system are known to hydrolyze at temperatures above 180 • C [42]. However, when the reaction system reaches 220 • C, further decomposition of cellulose and hemicellulose occurs.…”

“…Studies have demonstrated how variations in particle size and biomass-to-water ratio can impact key characteristics of hydrochar, including carbon content, porosity, and heating value [41]. By meticulously adjusting these parameters based on empirical data and scientific insights, researchers can fine-tune hydrothermal valorization processes to achieve maximal product yields and quality while advancing sustainable practices in chemical production [42].…”

The generation of platform chemicals and hydrochar is of great interest because they reduce dependence on fossil resources and contribute to climate change mitigation by reducing carbon emissions. The main objective of this study was to evaluate the effect of biomass particle size and biomass-to-water ratio in a hydrothermal conversion system for the generation of value-added products obtained from sugarcane bagasse. Biomass characterization was performed using proximal, elemental, and structural analysis; hydrothermal carbonization was carried out at 220 and 260 °C for one hour; and conversion was monitored using pH, conductivity, and IR spectroscopy. Platform chemicals were quantified using HPLC-IR. Hydrochars were characterized by using scanning electron microscopy and energy dispersive spectroscopy. Optimizing biomass particle size and water ratio is crucial for maximizing the yield of platform chemicals and hydrochar. The study’s outcomes revealed that specific combinations, such as a biomass-to-water ratio of 1:50 and a particle size of 212 μm at 220 °C, resulted in a substantial 31.07% yield of platform chemicals on a dry basis. This highlights the critical role these parameters play in influencing the production efficiency of valuable chemicals. Furthermore, variations in biomass particle size and water ratio also affect the characteristics of hydrochar. For instance, utilizing a biomass-to-water ratio of 1:50 and a larger particle size of 600 μm at 260 °C led to the production of hydrochar with higher carbon content and increased porosity. These findings underscore how adjustments in these factors can impact not only chemical yields, but also the properties and quality of the resulting hydrochar.
