AbstractNeedle coke was recognized as one of the most important precursor to produce ultra‐high power graphite electrode, commercial anode materials for lithium‐ion battery, and special graphite materials. It was generally accepted that the microstructure of needle coke has been acted as a key role on the quality of its derived graphite materials.

Modeling and Simulation of Petroleum Coke Calcination in Pot Calciner Using Two-Fluid Model
JOM, 2015The aim of this work was to establish a mathematical model for the analysis of calcining process of petroleum coke in a 24-pot calciner via computational fluid dynamics (CFD) numerical simulation method. The model can be divided into two main parts (1) heterogeneous reacting flow of petroleum coke calcination in the pot was simulated using a two-fluid ...

Rotary Hearth Calcining of Petroleum Cokes
2018While shaft furnaces and rotary kiln furnaces have been utilized for calcining of pet cokes and coals for a longer period, rotary hearth furnaces have been used for over 50 years, yet are still often overlooked when selecting a new coke calcining furnace.

Petroleum coke properties as influenced by particle size and calcination time and temperature
Chemistry and Technology of Fuels and Oils, 19731. An investigation has been made to determine how the porosity, yield of volatile components, and true and apparent densities of petroleum cokes are influenced by particle size and by calcination time and temperature. 2. It has been shown that the porosity, yield of volatile components, and true and apparent densities depend to a great ...

Effect of conditions of calcining and cooling petroleum coke on its physicomechanical properties
Chemistry and Technology of Fuels and Oils, 19731. Calcination of 30–40 mm lumps of petroleum coke under “thermal shock” conditions leads to an increase in the reaction rates for consolidation and ordering of crystallites; as a result, after 30 min of calcination, the cokes acquire the required physicomechanical properties, which are fully stabilized after 15–20 min of additional roasting.

Structural modification of petroleum needle coke by adding lithium on calcining
Coke and Chemistry, 2015Petroleum needle coke modified by lithium additives is studied with a view to producing high-strength carbon materials. Modification by calcining with lithium carbonate changes the structure and properties of petroleum coke. Since the atomic radius of lithium is less than the distance between the layers of acicular phase in the petroleum coke, the ...
