In particular, biochar, or biochar, can play an important role in reducing greenhouse gas emissions when used in blast furnaces in the metallurgical industry, either as a supplement to coke or as a replacement for PCI (excess coal). Here's exactly how it works:

1.Reduction of CO2 emissions: Biochar is a product of biomass pyrolysis and has a much lower carbon content compared to conventional coke. When used in a blast furnace, biochar can replace part of the coke, which reduces overall CO2 emissions, as biochar has lower CO2 emissions per unit of energy compared to coke.

2.Carbon retention: Biochar has the ability to permanently store carbon in the soil. When used in industrial processes, the carbon from the biochar remains locked in solid form and is not released as CO2. This helps reduce the total amount of CO2 in the atmosphere.

3.Reducing the need for coking coal: When biochar is added to the steelmaking process, some of the coke can be replaced by biochar. This leads to a reduction in the need for coke production, which also reduces the impact on the environment, as coke production involves significant emissions of CO2 and other pollutants.

3.Purpose in PCI technology: PCI (excess coal) involves the injection of coal into the blast furnace to improve the process and reduce the use of coke. Replacing part of the PCI with biochar can contribute to reducing CO2 emissions and improving energy efficiency.

Using biochar in a blast furnace is a sustainable option that can contribute to a significant reduction in the carbon footprint of industrial processes. In line with the strategy to reduce greenhouse gas emissions, this practice can become an important part of efforts to reduce environmental impact in the metallurgical industry.

@dragan ugrinov with very low carbon content won't it be affect the reduction and thereby overall productivity of blast furnace? Can you please share the %ge of carbon in biochar and the reduction reactions involving biochar?
