摘要
本文对聚乙烯和聚丙烯的混合物裂解成原料油进行了研究 ,在 44 0℃条件下 ,不同比例的聚乙烯和聚丙烯被裂解。结果发现 ,聚丙烯有最高的液体回收率。几种催化剂被应用到聚丙烯的裂解过程中。裂解产品组分的构成及催化剂的选择是本研究的主要内容。通过比较几种不同催化剂的催化结果发现 ,复合催化剂有更好的催化效果。
In this study, the methods of decomposing polyethylene (PE) and polypropylene (PP) into fuel oil were studied. After several mixtures with different ratios of polyethylene and polypropylene were respectively decomposed at 440℃, it was found that the pure polypropylene had highest productivity of both diesel and gasoline. Furthermore, several kinds of catalysts were chosen for the catalytic pyrolysis of polypropylene. The components of the decomposition products and the choice of catalysts are the main focus of this study. A comparison of the polypropylene decomposition results with the different catalysts showed that composite catalysts had better catalytic results for the pyrolysis of the polypropylene. The research results provide a new useful potential technique for the comprehensive use of waste plastics.
