Relationships among coking coals and related cokes characteristics: a statistical evaluation [PDF]
, 2018 From 61 coking coals, 36 coal blends were prepared. Using a pilot coke oven, cokes were prepared from both 61 coking coals (Type I cokes) and 36 coal blends (Type II cokes). Coals were characterized by 14 coal characteristics and cokes by Coke Reactivity

Gas-Modified Pyrolysis Coke for in Situ Catalytic Cracking of Coal Tar
ACS Omega, 2020 Modified pyrolysis coke can be used as a catalyst for tar cracking. In this paper, pyrolysis coke was used as a carrier for modification by using gases (H2O, CO2, and NH3), and the optimal modified gas was selected.

An Empirical Study on Laboratory Coke Oven-based Coal Blending for Coking with Tar Residue
Chemical Engineering Transactions, 2018 Tar residue is the solid waste produced in coking plants or gas generators. Utilizing tar residue as additive in coal blending for coking is an effective approach for coal coking in our country, not only improving the yield and nature of coking products,

Investigation of the fluid behavior of asphaltenes and toluene insolubles by high-temperature proton nuclear magnetic resonance and rheometry and their application to visbreaking [PDF]
, 2016 The fluid behavior of asphaltenes at elevated temperatures impacts coke formation in a number of hydrocarbon conversion processes, including visbreaking and delayed coking. In this study, the asphaltenes from a number of sources, namely, a vacuum residue,

Impact of small promoter amounts on coke structure in dry reforming of methane over Ni/ ZrO2
Catalysis science & technology, 2020 Coke deposition is one of the main challenges in the commercialisation of dry reforming of methane over supported Ni catalysts. Besides the coke quantity, the structure of the deposits is also essential for the catalyst lifetime.

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
