【摘要】 对近年来中孔分子筛催化废聚烯烃裂解反应的研究进展进行了综述,并对中孔分子筛与传统的小孔分子筛在催化废聚烯烃裂解反应中的结果进行了比较。指出中孔分子筛作为处理废聚烯烃的催化剂,具有很好的应用前景。建议今后应在提高中孔分子筛催化剂的酸强度、活性以及稳定性等方面做进一步研究。更多还原

【Abstract】 The progress of study on various mesoporous molecular sieves used in catalytic pyrolysis of waste polyolefins in recent years was reviewed. The catalytic pyrolysis results obtained over mesoporous molecular sieves were compared with those obtained o-ver traditional microporous molecular sieves. The development of the catalysts suitable for pyrolysis of waste polyolefins was prospected. It was suggested that the research works on increasing the acidity, activity and stability of mesoporous molecular sieves should be carried out in future.更多还原
