One of the options for reducing harmful emissions in the production of heat energy is the use of biomass, including in combination with industrial waste (for instance, coal and coke dust). Recent studies demonstrate that a mix of biomass and coal makes it possible to obtain a biocoal briquette with better characteristics, which is a motivating factor in the search for alternative sources of ...

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.
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 ...
Biomass Briquette OR Bio Coal is made from agricultural wastes and sawdust by high compression process without adding any chemical, glue or binder. It is thus 'binderless' technology product resulting in 100% natural ecofriendly solid fuel. Bio coal is a replacement for oil or coal, firewood; and can be used as a solid fuel in boilers ...
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 ...
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 production cost reflects the raw material cost, transportation, and energy consumption. Notably, wood biomass BioCokes can be used in cupola furnaces as an alternative to coal coke. The production process of wood biomass BioCokes is the same as that of BioCokes made from E. gracilis. The difference was in the first steps, whereas ...
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.
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.
Manufacturing biomass briquettes from biowaste is a process that can help to reduce environmental pollution. Biowaste, such as agricultural waste, can be converted into briquettes that can be used ...
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 biochar 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 biocoal produced obtained the highest HHV of MJ/kg with 120% energy yield ( Syguła et al., 2019 ).
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 ).
White coal, also known as bio coal or biomass briquettes, is a renewable energy source that serves as an alternative to traditional coal. Unlike fossil fuels, white coal is derived from agricultural and forestry waste, making it carbonneutral. ... The advantages of hydraulic press machines in the white coal manufacturing process are manifold ...
In the coalfired boiler for coalfired power generation provided by the present invention in the semicarbonization apparatus and manufacturing process for the production of biocoal that can be mixed with coal, the first screw of the transfer screw (4) and the drying unit (6) installed in a recuperative manner ( 8), the rotational speed of ...
Here, we propose to produce a new type of energy, biocoal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of the asprepared biocoals from the ...
determined. The biocoals were characterized in detail and a highlycontrolled study on biocoal hygroscopicity is presented. Optimal conditions for biocoal production ranged from a top temperature of 238 °C for maple wood to 286 °C for birch bark. Converting these two feedstocks to biocoal reduces hygroscopy by about 60 % and increases the ...
Life cycle assessment further shows that the biocoal production process could achieve net positive energy, financial, and environmental benefits. By using available biomass wastes as feedstock, China is expected to have a total biocoal production of 402 million tons of standard coal equivalent, which is equal to 13% of national coal consumption.
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.
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 ...
