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 ...
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 ).

Commonly, the torrefied product is termed biocoal or green coal and biochar when used as fuel and soil amendment. Based on the mode of operation, the torrefaction process can be practically classified into dry, wet and steam modes (Barskov et al. 2019). In dry torrefaction, biomaterial feedstock can be torrefied in nonoxidative; for example ...

Biomass briquetting is gradually emerging as a means of sustainable energy production. The interest in briquetting has been occasioned by the continuous rise in the cost of energy coupled with the need to harness efficient and affordable alternatives. Briquettes are produced through various means, ranging from a simple lowpressured technique to a highpressured technique. This, including the ...
To partially replace fossil coal and coke with climate neutral biocoal products that are adapted for use in the metal industry,, at the blast furnace, is a real and important opportunity to ...
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 ...
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.
1. Introduction Global warming is reduced by the development of clean technology for future security such as bio coal. Biomass is considered greenhouse gas neutral.

Life cycle assessment shows that the biocoal production process could achieve net positive energy, financial, and environmental benefits and grant China an opportunity to cut 738 million tons of CO2 emission by substituting an equal amount of coal with bio coal in 2030. A new type of energy is produced via a fast pyrolysis coupled with atmospheric distillation from lignocellulosic biomass ...
The biocoal production process was analyzed with two different operational aspects: (A) fast pyrolysis for biooil production and (B) fast pyrolysis in addition to atmospheric distillation for biocoal synthesis. ...

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 ...
I. INTRODUCTION Bio coal is a form of fuel produced by drying chopped wood over a fire. Biomass Briquetting is the process of converting low bulk density biomass into high density and energy concentrated fuel briquettes. Biomass Briquetting machines are of various sizes which converts biomass into solid fuels.
In this aspect, unutilized coal waste and sustainable biomass are considered major energy contributors to convert biomass blended coal fines as highquality solid briquettes. The present study integrates different briquette processing technologies to develop, coalbiomassbinder, coalbiomass (binderless), coalbinder, and carbonized biomass ...
Besides biooil production, directly blending deoiled microalgae with coal in form of pellets is considered an alternate strategy to produce solid fuel with high mechanical strength and improved ...
This process is an alternate strategy for converting the waste biomass into valueadded products like biochar, syngas and biooil. During the process, the lignocellulosic components like cellulose, hemicellulose and lignin undergo reaction processes like depolymerization, fragmentation and crosslinking at specific temperatures resulting in a ...
Biocoal is produced by processing dry biomass in an inert environment (no oxygen) at high temperatures, a process referred to as pyrolysis. Depending on the temperatures and the characteristics of the end product, the process may also be referred to as torrefaction. This process is commonly carried out using an indirectfired rotary kiln.
Biocoal briquette formulation and production . The biocoal briquette production process was reported by Adeleke et al. materials used were in accordance with the typical formulation shown in Table Table1 1 for the total briquette weight. Representatively, 8P7 M for blended binder composition implied that 8% pitch and 7% molasses were added as part of the total briquette weight, as ...

Construction of the project started in 2018; reactor #1 is expected to start production in 2022 and reactor #2 in 2024. The two reactors will each produce 40,000 tonnes of biocoal annually. Opportunities and challenges Sustainable biomass
Furthermore, the use of nonbiobased materials (domestic production waste, inorganic additives) for copelletizing with biomass also improves the quality of the pellet fuel and energy consumption to varying degrees. Although option (i) does improve pellet quality and optimise the pelletizing process, it has a limited impact on pellet quality.
Biofuels are playing an increasingly important role since they are an attractive alternative to fossil fuels, access to which has been limited. Moreover, they can help the European Union countries meet their climate and energy objectives. There is a growing interest in the production of biofuels from the organic fraction of municipal solid wastes as secondgeneration biofuels. Such a solution ...
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.
It is an energyefficient process to produce a highenergy biocoal that burns clean and takes a few hours to produce [2,7,8].
