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 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.
In pyrolysis, lignin, cellulose, and semicellulose, the main com ponents of biomass are quickly thermochemically decomposed in seconds to form smallmolecule compounds, in which about 50% of the volatiles can be condensed to form biooil. The carbon content of biooil ranges from 30 to 50%, and the high heating value (HHV) is about 15 MJ kg−1.

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.
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

Abstract. The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concrete ...
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.
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.
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%; (b) after step (a), cutting the fiber residue; (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 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 ...
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.
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.
Climate change and the unsustainability of fossil fuels are calling for cleaner energies such as methanol as a fuel. Methanol is one of the simplest molecules for energy storage and is utilized to generate a wide range of products. Since methanol can be produced from biomass, numerous countries could produce and utilize biomethanol. Here, we review methanol production processes, technoeconomy ...
