Potential for Reducing Emissions by Regulating O2, CO, and H2O in the Recirculation Gas in Iron Ore Sintering

steel research international, EarlyView.
This study investigates the potential for reducing emissions during the sintering process by selectively adjusting the O2, CO, and H2O content in the recirculation gas. Adjusting these components positively affects the sintering process, enabling the coke breeze content in the sinter mixture to be reduced.

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Preliminary Study on Unit Commitment for Renewable Energy Integration Considering Operation Cost and Life Cycle Assessment

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...
