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 ...
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).
From a technical perspective, the challenge of decarbonization involves two processes: chemical reduction for iron ore refining (process emission), commonly with metallurgical coal and coke, and from the high temperature heat sourced required to operate BF and other production reactors [ (Friedmann et al., 2019)].
Coffee Husk Coir Pith Jute Sticks Groundnut Shells Mustard Stalks Cotton Stalks Bio coal briquettes, primarily sourced from agricultural cellulosic wastes, are usually the preferred option. These byproducts are suitable for conversion into ecofriendly coal briquettes.
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 ...
It can be noticed that biocoal has more CC bonds, eventually making it a higher energycontaining material. Indeed, biocoal has carbon content comparable to lignite (%) ... For example, frictional pyrolysis is a unique process to produce biocoal from raw biomass [9], [71], [72]. Generally, a typical frictional pyrolysis unit consists of ...
Biochar is a carbonrich material that is made from biomass through a thermochemical conversion process known as pyrolysis. Don't worry if that all sounds like a mouthful—read on for an introduction to thermochemical conversion with a focus on biochar. You'll learn how biochar is made and the role it could play in building a sustainable ...
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.

Shalini Gautam a, Kaushik Kundu a, Lal Chand Ram b Add to Mendeley https://// Get rights and content • 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.
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.
The firm's biocoal product can be made from waste such as rice husks or peanut shells, and has a similar energy value as coal but with a smaller carbon footprint, managing director Yeung...
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.
This review article focuses on recent studies using hydrothermal carbonization (HTC) for producing hydrochar and its potential application as a solid fuel pellet. Due to the depletion of fossil fuels and increasing greenhouse gas (GHG) emissions, the need for carbonneutral fuel sources has increased. Another environmental concern relates to the massive amount of industrial processing and ...
The partnership with ArcelorMittal in Ghent starts with an initial delivery of 30,000 tonnes of biocoal to the Ghent blast furnace, which can be scaled up to 350,000 tonnes of biocoal on an annual basis. Need for change. Global steel production was billion tonnes for the year 2020, 70% of which was produced in blast furnaces using fossil ...
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.
You can produce these using a bio coal machine by burning them longer and making transportation of goods easier. The Material Used For Producing BioCoal Briquettes. Here is a list of some common materials to use in the process of producing biocoal briquettes: Bagasse as sugarcane production waste, Jute sticks, Coffee husk, Coir pith,
Our analysis focuses on applications of biocharcoal and biocoal (often mixed with coal for coke making) as replacements for solid fossil fuels in BFBOF steelmaking. Raw material inputs to the BF base model are shown in Table 6. We consider the possibility of biomass substitution both in the main reduction reaction process in the blast ...
The process of making biocoal briquettes begins with the preparation of the raw materials. Large . sized coal is crushed first using a jaw crusher and ball mill to reduce the size of the coal.
Green coal, also known as biocoal is an ecofriendly alternative to fossil fuels and is made from a combination of waste materials, such as agricultural residue and municipal solid waste (MSW). One of the key benefits of green coal is that it reduces the amount of CO2 emissions produced. For example, using 1 kg of biocoal as solid fuel ...
Climate change, socioeconomical pressures, and new policy and legislation are driving a decarbonization process across industries, with a critical shift from a fossilbased economy toward a biomassbased one. This new paradigm implies not only a gradual phasing out of fossil fuels as a source of energy but also a move away from crude oil as a source of platform chemicals, polymers, drugs ...
substitute for coal in most applications and in boilers. Briquettes can be produced with a density o f g/cm³ from loose biomass of bulk density to g/cm³ These can be burnt clean and therefore are ecofriendly arid also those advantages that are associated with the use of biomass are present in the briquettes.
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 ...
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 ...
