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.
The biocoal higher heating value (3032 MJ/kg) is in the range of the heating value of coal (3032 MJ/kg) used in the steel industries. Therefore, different biocoal production methods, such as pelletization, torrefaction, pyrolysis, hydrothermal carbonization, and steam explosion to produce biocoal, have been critically reviewed.
Biocoal with quality comparable to that of fossil coal can be produced by high temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low biocoal yield at high pyrolysis temperatures. This trade off suffers the economic feasibility of bio coal production.
Abstract. Biofuels comprise energyrich compounds produced from plant and microbebased biomass via a variety of biochemical, physical, and thermochemical processes. They serve as a feasible alternative to conventional fossil fuels for use in the transportation, industrial, residential, commercial, and powergeneration sectors.
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 ...
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.

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 ...

coal, biocoal, oil, and natural gas decreased rapidly as a large number of manufacturing plants stopped production. This is one of the examples where we can see a decrease in demand. So, the analysis of the performance and reliability of biocoal manufacturing plants with deviation in demand is quite important to avoid nancial harm. Kenny
