Due to global warming, technologies reducing CO2 emissions in the metallurgical industry are being sought. One possibility is to use biocoke as a substitute for classic coke made of 100% fossil coal. Biocoke can be produced on the basis of coal with the addition of substances of biomass origin. Blends for the production of biocoke should have appropriate cokemaking properties to ensure the ...
Coke corresponds to 2/33/4 of the reducing agents in BF, and by the partial replacement of coking coals with 510% of biocoal, the fossil CO2 emissions from the BF can be lowered by ~48%.

Biocoal, also commonly referred to as syn coal (synthetic coal), is created through the torrefaction of biomass. Biomass is a broad term that covers plant products and byproducts. From forest product residuals to sugarcane bagasse, the term biomass is used to describe anything with a cellulosic structure. And while biomass itself is used as a ...
Steel production is regarded as one of the primary greenhouse gas emission sources where fossil carbonbearing fuels are used as chemical reducing agents and a source of energy. Due to the dual role of carbon (iron ore reduction and heating) in the blast furnace ironmaking process, biocarbonbased renewable energy sources may serve as a prospective lowemission alternative to fossil fuel ...
Bio coal production process design. This procedure involves removal of mechanical impurities, crushing, homogenisation and soaking of the biomass. The BSG from the brewery are stored in spent grain buffer tank. The biomass is crushed and reduced to a grain size of <60 mm and sieved and transported to the blender. According to the experimental ...
The world's largest steel manufacturer will deploy a pioneering technology to make its production greener and contribute to the circular carbon economy. A blast furnace uses coal to chemically reduce iron ore into iron, which is then further processed into steel. It releases large amounts of greenhouse gases CO and CO2 in the process.
A method for producing a biocoal includes the following steps: (a) lowering the moisture content of a fiber residue obtained after oil extraction of oil palm fruit to less than 25%; (c) after step (b), pelletizing the fiber residue into shortfiber pellets; (d) drying the shortfiber pellets to reduce the moisture content of the shortfiber ...
The average modified combustion efficiencies increased, and burning rates were about 20% faster. The combustion of biocoal briquettes can reduce greenhouse gases like 38% CO 2 and 45% CH 4 but also hazardous air pollutants like 52% CO, 45% NO, and 29% PM effectively in comparison with the bituminous briquettes.
M. Tod, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013 Materials with ultrafine particle size There has been considerable difficulty in the commercial use of a number of finegrain materials and coal tailings as fuels or sources of heat, due to their ultrafine particle size, heterogeneity and high water content.
Besides pellets and briquettes, as shown in Fig. 2, BioCoke is also classified as a solid biofuel that can be used as a thermal energy 3 illustrates a single BioCoke production using a hydraulic press at a moderate temperature. BioCoke is produced by inserting dried lignocellulosic biomass waste into a molding cylinder, and then it is pressurized and heated until it reaches ...
Aim: CO2 neutral biocoal. Bio coal is a carbonneutral fuel that can replace fossil coal in industrial processes. It is produced within the process of Biogreen pyrolysis and carbonization of raw biomass performed within controlled temperature and residence time conditions. Thermal conversion of biomass, which is done under the oxygenfree ...
The carbonization of Nannochloropsis gaditana microalgae biomass was found to produce biocoal 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 biocoal has received attention for its ability to improve the ...
Therefore, it is urgent to develop a highquality coking coal production process with relatively mild parameters. Some experts have attempted to mix additives in order to produce higherquality biochar under relatively low operation parameters, found that additive itself had a certain influence on the product properties [30].
The biocoal resulting from the process of carbonization can be used as a fuel with a high calorific value. The remaining fraction undergoes a physicalchemical and catalytic conversion of inorganic particles into their clean, dry, and inert components. ... In the production process, it is mixed with small amounts of diesel fuel (up to 7%). As ...
Mass of the recovered process water was calculated by subtracting the dry mass of biocoal from the combined mass of process water and biocoal. Inorganic analysis. The biocoal and raw biomass to be used for analytical purposes were air dried and homogenised in a Retsch grinder.
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 ...
Pyrolysis is a wellestablished thermochemical process that involves the thermal breakdown of biomass into various fuel components such as biochar, biooil and pyrolysis gas (A. V. Bridgwater, 2011). Biochar is a carbonaceous solid fuel which is considered an economical substitute for coal (Budarin et al., 2013; Cheng et al., 2020; Sakhiya et ...
Process flow diagram for bio coal production from bagasse 4. Conclusion Sugarcane bagasse, a waste by product from the sugar processing industry can be used for the production of a solid fuel which has a high calorific value of around MJ/kg using the torrefaction technology. The bio coal can be used as a replacement to coal due to the high ...
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.
The main objective of this study is to determine the total decrease in the sulfur content in a blend of coal and biomass in which a fermentation process was carried out using a bioactivator for 24 h.
