Abstract:The catalytic conversion of polystyrene (PS) was studied in the presence of the materials type HZSM-5, CeO 2 , 10% CeO 2 /HZSM-5 and 20% CeO 2 /HZSM-5, which were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and nitrogen adsorption at 77K. The catalytic tests were performed via thermogravimetric analysis (TG) at heating rates of 5, 10 and 20˚C min −1 in a temperature range from 30˚C to 900˚C. For the tests, a ratio of 30% by mass of each catalytic material mixed with PS was used… Show more
