摘要

该研究研究了在基于Y和ZSM-5沸石混合物的催化剂存在下，聚乙烯和聚丙烯在真空蒸馏中以1-5 wt %的溶液形式催化转化为轻烯烃。讨论了反应条件和聚合物预处理方法对转化率和产物选择性的影响。在675℃时实现了聚烯烃的定量转化，产物主要为C2-C4轻烯烃。与纯真空馏分相比，聚合物溶液的裂解提高了轻烯烃的收率，提高了9.9%，其中丙烯的收率提高了5.2%。

Catalytic Conversion of Polyethylene and Polypropylene Wastes to Light Olefins

The study investigates catalytic conversion of polyethylene and polypropylene—in the form of 1–5 wt % solutions in vacuum distillate—to light olefins in the presence of a catalyst based on a mixture of zeolites Y and ZSM-5. The effects of reaction conditions and polymer pretreatment methods on the conversion degree and product selectivity are discussed. At 675°C quantitative conversion of the polyolefins was achieved, and the products mainly consisted of C₂–C₄ light olefins. The cracking of the polymer solutions enhanced the yield of light olefins compared to the pure vacuum distillate case, the enhancement reaching up to 9.9 wt %, including 5.2 wt % for propylene.

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
