چکیده انگلیسی
In this study, the efficient conversion of Helianthus tuberosus L. (Jerusalem artichoke) to sugar, 5-hydroxymethylfurfural (5-HMF), and levulinic acid (LA) were investigated using a Brønsted acid-catalyzed hydrothermal reaction. From this approach, the optimal amounts and reaction conditions for total reducing sugar (TRS), 5-HMF, and LA were as follows: 444 g kgâ1 of TRS yield (150.4 °C, 14.6 kg mâ3 sulfuric acid, and 9.8 min), 193 g kgâ1 of 5-HMF yield (166.0 °C, 4.6 kg mâ3, 30.8 min), and 323 g kgâ1 of LA yield (185 °C, 30.8 kg mâ3, 33.7 min). In terms of combined severity, the TRS and 5-HMF concentrations decreased linearly with increasing combined severity, whereas, the LA concentration was increased at a high combined severity factor. The H. tuberosus L. may be useful as a significant feedstock for the production of platform chemicals such as 5-HMF and LA.
