摘要：

With the intention of understanding chemical recycling of waste polymers, various kinds of zeolites were used as catalysts in the pyrolysis of polypropylene (PP). The effects of zeolites on the degradation temperature and pyrolyzed products of PP were studied. It was found that the degradation temperature of PP strongly depended on the type of zeolite used and the amount added. One type of HY zeolite (320HOA) was shown to be a very effective catalyst. Pyrolysis products, which were identified by using a coupled gas-chromatograph-mass-spectrometer, were also affected by the addition of zeolites. Some zeolites did not change the structure of the products but narrowed the product distribution to a smaller molecule region, while the HY zeolite led to hydrocarbons concentrated at those containing 4-9 carbons. Furthermore, some new compounds with cyclic structures were found in the presence of the HY zeolite. (C) 1996 Elsevier Science Limited
