Abstract
Pulverized Shenfu coal （SFC） was treated with ferric chloride （FeCI3· 6H2O） to prepare active coal via solid phase ion exchange. The active coal was blended with low-density polyethylene （PE-LD）. Differential scanning calorimetry （DSC） and other analytical methods were used to study the pyrolysis reaction and thermal decomposition kinetics of SFC, PE-LD, and PE-LD/SFC composites and the data were analyzed with Kissinger and Flynn-Wall-Ozawa methods. The activation energy of SFC was calculated as 113 kJ/mol at 340-380℃ and 149 kJ/mol at 520- 550 ℃. When adding 10% and 20% Fe3＋ modified SFC, the thermal activation energies at the low temperature （120-135℃） of PE-LD/SFC composites were 182. 87 kJ/mol and 250. 62 kJ/mol. When adding 10% Fe3＋ modified SFC, the reactivity of coal and PE-LD was better, so there must be Coordinated action between two points.关键词
