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 ...

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%. Coking coal blends with 5% and 10% additions of biocoals (pretreated biomass) of different origins and pretreatment degrees were carbonized at laboratory scale and with a 5% biocoal addition at ...

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 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 ...

The use of pretreated biomass (biocoal) as a part of the raw material blend for cokemaking could be one possible way of reducing the fossil CO2 emissions linked to the BF process. The advantage of replacing part of the fossil coal with biocoal is that the biomass regeneration time is comparatively short [4] and the effects on global warming

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.

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.

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.
