| Abstract |
Sludge is the unwanted solid waste produced during the treatment of industrial wastewater. The
hydrothermal carbonization process (HTC) can be used to convert sewage sludge into a coal-like solid
fuel. The effects of solid-to-liquid ratio and feed water pH on the physicochemical properties of hydro-
chars were investigated. According to the results, hydrothermal treatment enhanced the fuel character-
istics of hydrochar with a high HHV and fixed carbon. Adding 0.8 M acetic acid resulted in the highest rate
of energy recovery at 96.98 %. The observed H/C and O/C atomic ratios of HTC-0.4AA have been lowered
to levels comparable to lignite coal. ICP-OES confirmed the presence of the metal in the hydrochar prod-
uct. Examining the thermogravity analysis of raw materials and hydrochars with a TGA analyzer was then
used to determine the combustion kinetics. In addition, combustion characteristics indicate that HTC
improves the S combustibility index |
