Effect of operating conditions on hydrochar production from digestate
September 15-20, 2019
Hydrothermal carbonization (HTC) is a thermo-chemical process that uses water under subcritical conditions to convert biomass into a C-rich product known as hydrochar. HTC process takes place at relatively low temperature (generally in the 180–250°C range) under autogenous pressure. The process conditions promote the hydrolysis and dehydration reactions generating condensed aromatic structures having a high concentration of oxygenated functional group (OFG); these characteristics make hydrochar a promising candidate in several high-value applications [1–3]. HTC can be applied to a number of feedstocks, ranging from simple carbohydrates (i.e. glucose, cyclodextrins, fructose, sucrose, cellulose, starch, etc.) to more complex biomasses (such as lignocellulosic biomass, agricultural residues, municipal biowaste, etc.).
