Definition

Hydrochar is a carbon-rich solid material produced at mild temperature conditions in a closed atmosphere from any kind of wet waste including municipal waste, digested sludge, and agricultural residues. The higher carbon content, higher heating value, and lower ash content of hydrochar make it a suitable material for use as a fuel. The abundance of surface functional groups and acidic surfaces makes it a low-cost adsorbent for pollutant removal from wastewater (Sun et al. 2014).

Hydrochar Production

Hydrochar is produced in a sealed vessel known as a hydrothermal reactor under subcritical region of water at 180–250 °C and self-generated pressure for a specific period. The structure of the reactor used for hydrochar production is given in Fig. 1. Since hydrochar synthesis involves wet feedstock conversion, feedstocks with higher moisture content can be directly utilized in...
