Challenges and opportunities of hydrothermal carbonisation in …

However, it is important to note that the properties of a co-hydrothermal carbonisation are likely to be different to those that use this method of estimation. Nevertheless, total dry mass, total water content and total mass of HC mix is calculated as 95.42 t per year, 3.66 t per year and 99.08 t per year, respectively.

Free Full-Text | Process Water Recirculation during Hydrothermal Carbonization of …

21/4/2021· Hydrothermal carbonization (HTC) is considered as an efficient and constantly expanding eco-friendly methodology for thermochemical processing of high moisture waste biomass into solid biofuels and valuable carbonaceous materials. However, during HTC, a considerable amount of organics, initially present in the feedstock, are found in the process …

Spectroscopy of Hydrothermal Solutions 18: pH-Dependent …

2/11/2001· The kinetics of decarboxylation of the α-substituted acrylic acid itaconic acid were analyzed at 280−330 °C, 275 bar, and solution pH25 = 0.8−5.75 using an FTIR spectroscopy flow reactor. As the pH was increased, the observed rate constant initially decreased to a minimum at pH25 = 1.82, then increased and reached its maximum at pH25 = 3.75, and then decreased …

Hydrothermal Conversion of Spent Sugar Beets into High-Value …

27/8/2020· As the main field of interest in this study was the conversion of the initial biomass to intermediates, the reaction time started when the reactor reached the reaction temperature. Increasing the operating temperature from 160 °C to 200 °C led to an almost time-independent reduction of VM ( Table 2 ).
