In addition, the HTC is a thermochemical conversion process operated under mild temperatures with autogenerated pressure which could produce solid material called biocoal or hydrochar, depending on its application, carbon content, and energy property [11]. Therefore, in this study, an energy densified biocoal is required and extended to focus.

Assessing the potential of selected biomass residues as feedstock for biochar preparation at 550 °C. Blend of LVC coal with biochar has potential for synthesis of biocoke a substitute for metallurgical coke. Optimum coaltobiochar ratio for biocoke is 70:30 at 1000 °C for CSC and 900 °C for GSC; and 80:20 at 900 °C for SDC.

Metal production, and especially iron orebased steel production, is characterized by high fossil CO2 emissions due of the use of coal and coke in the blast furnace. Steel companies around the world are striving to reduce the CO2 emissions in different ways,, by use of hydrogen in the blast furnace or by production of iron via direct reduction. To partially replace fossil coal and coke ...

In the hydrothermal treatment process, biochar as a solid and carbonrich product is obtained from biomass. Generally, wet biomass with lignocellulosic content is converted into a kind of coal named as biocoal, biochar, or hydrochar (Ong et al., 2020; IbarraGonzalez and Rong, 2019; Zhu et al., 2021; Maki et al., 2021 ).
