Effect of Extracted Compositions of Liquefaction Residue on the Structure and Properties of the Formed-coke

open access: yesMATEC Web of Conferences, 2016
The purpose of this paper is to study the effect of extracted compositions of the de-ash liquefaction residue (D-DCLR) on pyrolysis products yields, compressive strength and composition of the formed-coke, which was prepared by co-pyrolysis of the low ...

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

open access: yesJournal 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

Utilization of Renewable Carbon in Electric Arc Furnace-Based Steel Production: Comparative Evaluation of Properties of Conventional and Non-Conventional Carbon-Bearing Sources

open access: yesMetals, 2023
Conventional (anthracite, calcined petroleum coke, and coke) and non-conventional (biochar, and biocokes (3 wt.% torrefied wood, and 3 wt.% petroleum coke + 3 wt.% charcoal)) carbon-bearing sources have been studied for their use in electric arc furnace (

Enhancing the strength of formed coke from rice husk via sequential hydrothermal treatment, hot briquetting, and carbonization

open access: yesIndustrial Crops and Products
The growing severity of energy shortages and environmental challenges underscores the necessity of developing sustainable biomass energy. Rice husk (RH) biomass is abundantly available but often incinerated or discarded, causing environmental issues and ...

Effect of inertinite-rich coal on metallurgical coke strength and porous microstructure [PDF]

open access: yesREM: International Engineering Journal
The consumption of coals without coking properties in coal blends for coke production is a challenge, precisely because of their lack of coking properties, and in some cases, high contents of macerals from the inertinite group, which are known to ...

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

open access: yes, 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

Expanding pitch-coke production

open access: yes, 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.

Resolving and Controlling Silicoaluminophosphate Zeolite Intergrowths and Mixtures

open access: yesAdvanced Science, EarlyView.
Low‐dose electron microscopy enables atomic‐resolution imaging of beam‐sensitive SAPO‐34/18 intergrowths, revealing their stacking sequences and spatial distributions under controlled Si content and SDA ratio. This work establishes a methodology linking controllable synthesis with atomic‐resolution microscopy to investigate structure–property ...

Quality evaluation of metallurgical coke produced with sawdust and different mixtures of coal

open access: yesREM: International Engineering Journal, 2021
The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost.
