Abstract
The catalytic activities of mesoporous H–MCM-41 aluminosilicates of different compositions in degradation of polypropylene and a polypropylene-polyethylene mixture into gasoline-range fraction hydrocarbons were compared. A higher yield of the target products (86 wt %) was observed for the sample with a lower aluminum content. Using the results of chromatographic analysis of the catalyzate for the content of the gasoline-range fraction, both saturated and unsaturated hydrocarbons, dominated by products with cyclic structure, were identified in all the samples studied. In the presence of the H–MCM-41 sample with a lower silica modulus, a larger amount of condensation products with a higher calorific value arose from polypropylene degradation. Mesoporous aluminosilicates H–MCM-41 can be regarded as effective catalysts for thermocatalytic conversion of polypropylene to produce the gasoline-range fraction.

MCM-41型介孔材料存在下聚烯烃的催化转化
摘要
比较了不同组成的介孔 H-MCM-41 铝硅酸盐对聚丙烯和聚丙烯-聚乙烯混合物降解为汽油馏分烃的催化活性。对于铝含量较低的样品，观察到目标产物的产率较高（86 wt%）。利用催化剂对汽油馏分含量的色谱分析结果，在所有研究的样品中鉴定出以环状结构产物为主的饱和烃和不饱和烃。在具有较低二氧化硅模量的 H-MCM-41 样品存在下，聚丙烯降解产生大量具有较高热值的缩合产物。
