Abstrakt: A possible route to remove Fe catalyst from graphitized carbon black synthesized in Boudouard's reaction is employment of gaseous chlorine in role of carrier. This process was explored by means of DTA method using the equipment designed in the laboratory. Obtained results demonstrate the complexity of processes occurring in systems containing Fe, C and Cl2. Reactions in the system are highly influenced by the geometry of reacting solids. Process of FeCl3 intercalation between graphite layers was observed analyzing DTA curves. The amount of Fe in the raw product of Boudouard's reaction was determined during the process of chlorination. Obtained results indicate that Cl2 stream does not remove all the Fe even at high temperatures and prolonged chlorinating time. [ABSTRACT FROM AUTHOR]
