Abstract :This work examined the hydrothermal breakdown of biomass into platform chemicals, including acetic acid (AA), formic acid (FA), 5-hydroxy methyl furfural (5-HMF), and levulinic acid (LA). Chicory was selected as feedstock because of its high potential to produce valuable chemicals. Reactions were performed with BSA (benzenesulfonic acid) and LABSA (linear alkyl benzene sulfonic acid) as sulfonic acid catalysts. The studies were conducted with different catalyst concentrations (100, 300, and 600 mM) for 110 minutes at 200 °C with a biomass-to-solvent ratio of 1g/25 mL. The variation of product yield and composition on parameters such as time, sulfonic acid concentration, and type of catalyst were investigated. The maximum levulinic acid yields in wt.% achieved through the experiments of this study were 22.65 wt.% (9.05 g/L) for 600 mM BSA and 85.93 wt.% (34.37 g/L) for 600 mM LABSA at 200 °C.
