The influence of titanumoxide on PAHs behavior during the process of coal pitch termolysis

摘要

Paper presents researches results of coal pitch thermal preparation (thermolysis) catalyzed with TiO2 and carried out within temperatures range form 300°C up to 410°C. It has been proved that due to catalytic influence of titanium dioxide the contents of 16 PAHs according to EPA decreases and the contents of benzo(a)pyrene is 5 times smaller. Lower content of determined 4, 5 and 6-ring hydrocarbons in both pitch and liquid product samples obtained during pyrolysis has also been observed.
