Fluidization hydrodynamics in the calcination of petroleum coke
Chemistry and Technology of Fuels and Oils, 19691. A method has been selected and the bulk density determined, as a function of temperature, of cokes of different granulometric composition. 2. The porosity of petroleum coke has been determined, and found to have an average value of ɛ = 0.4; the apparent density has also been determined. 3.

Lining of the Rotary Kilns for Petroleum Coke Calcination
Refractories and Industrial Ceramics, 2019The paper provides a brief description of the technological process and design of the rotary kilns for petroleum coke KEP-1 and KEP-2 calcination, as well as specifies the lining requirements for some parts of such kilns. The lining bricklaying specifics and main techniques with respect to rotary kilns (including foreign designs) are demonstrated.

The problem of sulfur content in calcined petroleum coke
JOM, 1990The sulfur content of petroleum coke has steadily increased in recent years, and forecasts show levels will rise even further. This increase in sulfur content comes at a time when environmental awareness is at a peak, and regulatory restrictions are likely to place limits on the amount of sulfur permitted.

Petroleum coke calcination processes ? present and future
Chemistry and Technology of Fuels and Oils, 1986The authors discuss the calcination of petroleum coke. The requirements imposed on different types of calcinated petroleum cokes in the USSR are summarized. The elemental content of petroleum cokes is shown. Basic factors in the calcination process are examined, such as raw material, temperature, process time, and heating rate.

Modeling the Change of Green Coke to Calcined Coke Using Qingdao High-Sulfur Petroleum Coke
Energy & Fuels, 2015This paper presents macromolecular models of sulfur-containing Qingdao petroleum. The results were investigated with ultimate analysis, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The models showed that organic sulfur, nitrogen, and oxygen in the coke were mainly in the forms of thiophene-containing polycyclic ...

Petroleum Coke. Feedstock Resources and Calcination Technologies
Chemistry and Technology of Fuels and Oils, 2005Coking is an important and comparatively inexpensive process for exhaustive refining of crude oil. The total number of coking units in the world is over 160. The highest number is in the USA, with approximately 70, China with 24, and Russia with a total of 8 [1, 2].
