In the hydrothermal treatment process, biochar as a solid and carbon-rich 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; Ibarra-Gonzalez and Rong, 2019; Zhu et al., 2021; Maki et al., 2021 ).

The carbonization of Nannochloropsis gaditana microalgae biomass was found to produce bio-coal that is similar to bituminous coal used in thermal power plants. Currently, microalgae that capture CO 2 while they are in the growth stage are considered a source for the production of biofuels. The carbonization of biomass for producing bio …

In addition, it reduces the amount of coal used. Also, bio-coal and bio-coke have a faster burning rate and are more effective at converting fuel to heat [6], [27]. Recently, Mkhwanazi et al. and Singh et al. have summarized only hydrothermal carbonization processes for bio-coal production [28], [29].

In this new effort, the team in China has found a way to create a type of bio-coal that is much greener than natural coal. Prior efforts to produce a type of fuel from plant waste have led to the ...

Here, we propose to produce a new type of energy, bio-coal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of …

In conclusion, white coal, or bio-coal, is a sustainable and renewable energy source produced from agricultural waste and biomass residues. Its production process offers several advantages, including its renewable nature, high energy efficiency, environmental friendliness, easy storage, and versatile applications.

Metal production, and especially iron ore-based 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, e.g., by use of hydrogen in the blast furnace or by production of iron via …

The bio-char produced at 350 °C also has higher content of fixed carbon and hydrogen as well as lower content of ash and nitrogen. For optimized torrefaction condition of 280 °C and 60 min, the bio-coal produced obtained the highest HHV of 17.9 MJ/kg with 120% energy yield ( Syguła et al., 2019 ).
