The Effect of Metallic Iron Particle on Coke-Matrix after Coke CO2 Gasification Reaction

Journal of Thermal Science and Technology, 2011
In order to prevent pulverization and fracture of metallurgical coke, control of gasification reaction part in coke lump and embrittlement behavior is important. Addition of catalyst particle is an effective and a simple method for enhancement of the CO2

Expanding pitch-coke production

, 2011
The possibility of producing pitch coke from moderate-temperature pitch with the introduction of 10-30% dusty carbon fillers is investigated. The influence of graphitized dust and coal dust on the yield and quality of pitch coke is demonstrated.

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Zeolite deactivation during hydrocarbon reactions: characterisation of coke precursors and acidity, product distribution [PDF]

, 2008
The catalytic conversion of hydrocarbons over zeolites has been applied in large scale petroleum-refining processes. However, there is always formation and retention of heavy by-products, called coke, which causes catalyst deactivation. This deactivation

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
