摘要: In this study, effects of reaction temperature and time on both solid hydrochar HTC process liquid products were studied for hydrothermal carbonization (HTC) cellulose, wheat straw, poplar. A novel slurry sampling system was designed used with an 18.6L Parr reactor 0-480 min in 200, 230, 260 °C. Sugars (sucrose, glucose, fructose), HMF, furfural found maximum lower time. However, they degrade following first order degradation kinetics. Activation energies total sugars (glucose, fructose, sucrose, xylose), furfural, HMF straw poplar 95-127, 130-135, 74-90 kJ mol(-1), respectively individuals cellulose than others. Organic acids (acetic acid, formic lactic acid) phenolic compounds (phenol, catechol, guaiacol) increasing higher severity.
