Metallurgical Industry Applications

Applications in the Iron and Steel Smelting Industry

Industrial Biochar as a Reducing Agent and Energy Source

Biochar is a renewable carbon source that can replace fossil carbon (such as coke and coal) as a reducing agent and energy source in metallurgical processes like steel production. It can reduce greenhouse gas emissions, decrease dependence on fossil fuels, and improve energy efficiency.

Blast Furnace Application

Biochar can be used in various stages of blast furnace operations, including fuel injection, sintering, and coking. Within the blast furnace, biochar can serve as a substitute for coke or be added through tuyere injection.

Electric Arc Furnace (EAF) Application

In electric arc furnaces, biochar can be used as a carbon source or a fluxing agent. The steelmaking process in an EAF requires the addition of carbonaceous materials for slag formation and adjusting the composition of the molten steel.

Applications of Torrefaction Products in the Metallurgical Industry

Torrefaction products are biomass materials processed through torrefaction, characterized by high energy density and carbon neutrality. As a substitute for fossil fuels, they contribute to achieving industrial carbon neutrality.

Advantages of the Torrefaction Process:

Increased Energy Density

The energy density of torrefied biomass can increase by 20-30 %.

Improved Hydrophobicity

Torrefied biomass is hydrophobic, making it easier to store and transport.

Enhanced Grindability

Torrefied biomass is easier to grind, making it compatible with existing coal pulverizing system.

Construction/Building Materials Industry Applications

Biochar as a Concrete Additive

Biochar can be used as an additive in building materials, such as a concrete additive, to enhance its performance and durability. Utilizing carbon from biomass pyrolysis in cement-based materials strengthens mechanical properties and durability, and it is noted as a pioneering strategy in the concrete industry.

Biochar Bricks

Biochar can be mixed with materials such as clay and cement to produce building bricks.Biochar, as a carbon-sequestering building material, can fix carbon for extended periods. Incorporating carbon derived from biomass into building materials is one pathway to achieving carbon neutrality in the construction industry.
