Gasification of coal-derived chars in synthesis gas mixtures under intraparticle mass-transfer-controlled conditions [PDF]

, 1986
A model has been formulated to describe the quasi-steady-state gasification of coal-derived chars in gas mixtures where both the reactants carbon dioxide and steam, and the gasification products carbon monoxide and hydrogen are present.

Bottom‐Up Strategy Toward 3D Porous MXene/MoS2 Nanosheets/Graphene Nanoarchitectures as Highly‐Efficient Hydrogen Evolution Electrocatalysts

Rare Metals, EarlyView.
ABSTRACT As a core component in the electrochemical water splitting system, the cathode catalyst is capable of boosting the kinetics of the hydrogen evolution reaction (HER), while the scarcity and expenditure of current noble metal‐based electrocatalysts seriously restrict the large‐scale commercial development of hydrogen manufacturing devices. Here,

Smart Waste, Smarter World: Exploring Waste Types, Trends, and Tech‐Driven Valorization Through Artificial Intelligence, Internet of Things, and Blockchain

Sustainable Development, EarlyView.
ABSTRACT Global municipal solid waste generation is projected to exceed 3.8 billion tonnes annually by 2050. This makes the need for smart, inclusive, and scalable waste valorization systems more urgent than ever. This review critically explores the shift from conventional waste management to intelligent, technology‐driven solutions aligned with ...

Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, EarlyView.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions
