Some physicochemical properties of petroleum pyrolysis cokes
The objective of the present work was to investigate the structure and reactivity of cokes and fillers from petroleum. The tests were carried out with KNPS and KNPE petroleum pyrolysis cokes, KZI needle coke obtained on a delayed coking unit, and coke obtained from KO oxidized petroleum residue. The original cokes were subjected to a preliminary thermal treatment in an inert atmosphere and the calcined samples were then used to determine the reactivity, the ash content, the specific surface, the content of impurities, the porosity, and xray characteristics. The presented data show that suppression of the catalytic effect of the impurities by impreganation with manganese phosphate is effective for cokes with low TTT.
