Thermal and catalytic degradation study of polyethylene and investigation the catalytic effect of X-Zeolite and Silica-Alumina on degradation kinetic
چکیده
The thermal degradation of polyethylene (PE) was carried out in the absence and presence ofcatalystes X-Zeolite and Silica-Alumina at different temperatures. The optimum PE/Catalysisratio was 0.25:0.05 g/g, which produced highest degradation value. PE and PE/Catalysis werecharacterized by thermogravimetric analysis. The thermal degradation properties of polymerhave been studied by Infrared spectroscopy–FT-IR. Experimental data indicated that thepresence of catalysis greatly increased the rate of degradation of PE. The activation energy ofdegradation for pure polyethylene and polyethylene in presence catalysises was calculated byArrhenius equation and Ozawa method. Activation energy follows the order PE Alumina
