摘要
选取高密度聚乙烯、低密度聚乙烯、低聚物、聚丙烯、聚苯乙烯为试样，以热重分析法分析了这些常见塑料的热解动力学性质。从热裂解和催化试验研究发现，相同的试验条件下，乙烯聚合物降解时直链烃比较多，聚丙烯的支键产物比较多，聚苯乙烯的单体产量高。从试验结果可见，乙烯聚合物降解后宜于制取蜡产品、聚丙烯宜于制取汽油、柴油，聚苯乙烯宜于制取苯乙烯单体。
Cracking kinetics of HDPE, LDPE, low polymer, polypropylene and polystyrene are studied by thermogravimetric analysis. The thermal cracking and catalytic cracking of these plastics indicated that polyethylene wastes are suitable for making wax by thermal cracking, polypropylene wastes are suitable for making gasoline and diesel fuel by catalytic cracking, and polystyrene wastes are suitable for making styrene monomer by thermal cracking.
