Carbon Energy, EarlyView.Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Carbon Innovation, EarlyView.Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

The petrochemistry of coal ash slags. Part 3. Behavior of the rosebud slag-limestone system
Fuel Processing Technology, 1981 Rosebud subbituminous coal has been used as a feedstock in many coal conversion pilot plants, including the BI-GAS and Grand Forks Energy Technology Center slagging gasifiers. Limestone has been investigated as a fluxing agent for Rosebud slag. Slag viscosity decreases as an increasing function of limestone addition to about 30% limestone, but further ...

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.

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This paper examines whether occupational pension funds (OPFs) apply a strategic and long‐term logic when assessing ESG practices in their investee firms. Using discourse analysis of semi‐structured interviews with asset managers and workers' representatives, we examine whether Spanish OPFs look beyond compliance‐driven CSR and consider the ...
