The influence of a coking crude on the structure of calcined petroleum coke and the subsequent structural changes in coke induced by high-temperature treatment up to 2400°C were investigated. The surface morphology, crystallite height (Lc), and interlayer spacing (d002) were determined as a function of temperature and heating time. High-temperature treatment had a positive effect on the coke structure so that with increasing temperature and heating time, the crystallite size increased while the interlayer spacing decreased. The results showed that not only temperature but also coking crude were major factors influencing the structure of petroleum coke.
