| Abstract: | Вивчено фізико-хімічні характеристики та
кінетику згоряння нафтового коксу або пек-коксу (НК). Ви-
значено, що НK має високий вміст карбону, зв‘язаного карбону
та високу теплотворну здатність, і низький вміст сульфуру та
золи. Показано, що температура займання НК коливається в
межах 764–795 К, пік розкладання 808–875 К та температура
вигорання 857–933 К. За допомогою аналізу продуктивності
згоряння та реакційної здатності визначено коефіцієнт
запалювання, коефіцієнт перетворення, коефіцієнт вигорання
та характеристичний коефіцієнт згоряння. Визначено також
енергію активації та предекспонентний множник. Показано, що
НK дуже реактивний під час згоряння всупереч даним
літератури. На основі проведених досліджень встановлено, що
спалювання є практичним підходом для видобутку енергії з НК. 1The study examined the physico-chemical characteristics and combustion kinetics of petroleum coke or petcoke (PCK). The results revealed that PCK contains significantly high carbon, fixed carbon, and calorific value with low sulphur, and ash content. The combustion characteristics of PCK revealed the temperatures of ignition ranged from 764 to 795 K; peak decomposition from 808 to 875 K and burn-out from 857 to 933 K. The combustion performance and reactivity analyses were examined based on the ignition ratio, devolatilization ratio, burnout ratio, and combustion characteristic factor were performed. The activation energy and preexponential factor were determined also. The results revealed that PCK is highly reactive during combustion contrary to previous reports in the literature. Overall, the findings demonstrate that combustion is a practical approach for energy recovery from petcoke. |
