Carbon Innovation, EarlyView.Graphite electrodes are revisited as strategically important carbon materials for electric arc furnace steelmaking. By correlating three‐dimensional microstructural complexity with fracture energy, this work reveals a fundamental trade‐off between graphitization and energy dissipation, providing a data‐driven framework for the rational redesign of ...

Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Mass and energy based modelling of EAF steelmaking scenarios using scrap and hydrogen reduced DRI as raw materials [PDF]
Pressure for radical reduction of CO2 emission in steel industry favours EAF steelmaking using scrap and hydrogen reduced iron (H2DRI) as raw material over traditional blast furnace-based production.

Chemie Ingenieur Technik, EarlyView.Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

Process Gas Transitions in the Steel Industry—Planning Corridors for Chemical Utilization
Chemie Ingenieur Technik, EarlyView.Scenario‐based planning corridors link route‐ and pace‐dependent steelworks off‐gas availability (BFG, BOFG and SAFG) to a 1000 mtpd methanol demand over 2030–2060, revealing pace‐limited BFG concepts and route/site‐size limits for CO‐rich operation and motivating early CO2 tie‐ins as retrofit‐friendly safeguards.

Hot Metal Temperature Forecasting at Steel Plant Using Multivariate Adaptive Regression Splines
Metals, 2019 Steelmaking has been experiencing continuous challenges and advances concerning process methods and control models. Integrated steelmaking begins with the hot metal, a crude liquid iron that is produced in the blast furnace (BF).

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.
