Torrefaction removes moisture and volatiles from biomass, leaving biocoal. Torrefaction of biomass,, wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates ...

The higher volatile content of biomass [22], [23] may affect fluidity during the plastic phase of the cokemaking process, ultimately leading to biocokes with high coke reactivity index (CRI) and low coke strength after reaction (CSR) compared to conventional cokes [24]. The feed size also affects the mechanical properties of the biocoke.

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 ).
Fossil fuels coal and coke represent the main source of energy in the iron and steel industry. Biomass utilization practices for iron and steel making are one promising approach for partial substitution of coal and coke to mitigate CO 2 emissions. The main opportunities for biomass application in iron and steel making can be summarized in Fig. (Jahanshahi et al., 2013; Norgate et al., 2012).
Creating biochar actually reduces CO2 in the atmosphere because the process takes a theoretically carbonneutral process of naturally decaying organic matter and turns it carbonnegative: When plants decay, they emit CO2, which other plants eventually absorb, and the cycle continues. Biochar stabilizes that decaying matter and accompanying CO2 ...
Biocoal may refer to: Hydrothermal carbonization, a moderate temperature waterbased process to convert biomass to a coallike substance. Torrefaction, a mild form of pyrolysis to convert biomass to a charlike substance.
Experimental research was carried out on the manufacturing of biocoal briquettes from a blend of two different types of lowquality coal and biomass waste in the absence of coal carbonization, where the third blend of the material was fermented by adding a bioactivator solution before pressurizing the components into briquettes. The coal samples from CaringinGarut Regency (BBGarut) had ...
The most sortout agricultural residue that finds great use for bioethanol production is the corn stover, and the rice and wheat straws. These crops are abundant all through the year, leaving behind enormous waste during its processing; however, very little attention is given to its biofuel production potential.
One way to make the coal substitute is a process known as hydrothermal carbonisation (HTC), which uses superheated water under pressure to produce biocoal in a few hours. It normally takes millions of years for fossil coal to form geologically. 'It's really a very simple and stable process, because it acts like an acceleration of the ...
Furthermore, the FT process has the major advantage of accepting different carbonbased inputs, making this process appropriate for using different sources as feedstock such as waste biomass, coal, and natural gas (Liu et al., 2013). Furthermore, the maximum energy efficiency of the FT fuel derived from biomass (77%) is higher than that of the ...

Abstract. The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concrete ...
The briquetting process is the conversion of agricultural waste into uniformly shaped briquettes that are easy to use, transport, and store. The idea of briquetting is using materials that are unusable, due to a lack of density, and compressing them into a solid fuel of a convenient shape that can be burned like wood or charcoal.
