【摘要】 采用热裂解、热裂解—催化改质、催化裂解等方法将废聚丙烯制成汽、柴油馏分。研究发现废聚丙烯垃圾可以不经过任何处理直接作为裂解原料制取油品。分析了不同工艺条件下的汽油馏分及气体组成 ,测定了汽油馏分的辛烷值以及柴油馏分的十六烷值 ,并对三种方法进行了技术评价 ,认为热裂解—催化改质是最为实用的油化方法更多还原

【Abstract】 Pyrolysis,pyrolysis catalytic upgrading and catalytic pyrolysis have been developed to convert polypropylene waste to diesel and gasoline fractions The result shows that polypropylene waste can be used as feedstock for cracking to oil without being cleaned The components in gaseous products ,gasoline and diesel fractions were analyzed and the RON for the gasoline obtained by three methods is 80,87 3～90 8,84 5～88 6 and the cetane number index for the diesel obtained are 45 35,42 42～42 72,40 56～45 30 respectively Three methods were evaluated in a comprehensive view and the result shows that pyrolysis catalytic upgrading is the most feasible way to convert plastic waste to oil in a large scale [更多还原
