Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Systematic Learning and Pedagogy Through a Modular, Progressive‐Based Simulation Modeling Framework for Complex Systems

Systems Engineering, EarlyView.
ABSTRACT Smart Transportation Systems (SmTS) will exceed complex systems with their classification as complex, sociotechnical, and AI‐based systems. Possessing a toolkit that helps systemically understand, analyze, and assess these systems will be advantageous in the early stages of the systems engineering (SE) lifecycle, and Agent Based Models (ABMs ...

Do Financialization and Innovation Enhance Environmental Sustainability in Sub‐Saharan Africa?

Thunderbird International Business Review, EarlyView.
ABSTRACT This study addresses the perception of Sub‐Saharan Africa (SSA) as a region with limited financial capabilities and technological advancement to enhance environmental sustainability. Conducted across 24 SSA countries from 2000 to 2021, the research employs instrumental IV and panel quantile regressions.
