【摘要】 本文设计并搭建起一套小型的废塑料热解-催化改质实验装置,在校内实验与理论研究相结合的基础上对废塑料热裂解及其对裂解气催化改质进行了深入研究。本文通过实验证明,PP和LDPE均有自己的热裂解温度特性;研究了各种反应条件,如热解温度,催化剂的种类及其加入量,催化改质温度对PP和LDPE裂解的液体收率、残渣收率、不凝气收率以及汽油馏分、柴油馏分和重油馏分的影响。针对目前废塑料裂解中使用的催化剂昂贵以及种类少的现状,采用造粒、高温烧成工艺与添加造孔剂相结合的方法,制备轻质、球型、多孔粉煤灰陶粒催化剂。更多还原

【Abstract】 A miniature-testing device with thermal pyrolysis-catalytic reforming of waste plastic was designed and constructed in this work,and based on the test in laboratory and theory,this work made a deep research on the pyrolysis of waste plastic and the catalytic reforming of cracking gas. Experiment demonstrated that PP and LDPE has its own special characteristic of thermal pyrolysis versus temperature. Effects of variety of reaction conditions such as the pyrolysis temperature, the kind of catalyst and the quantityof catalyst, catalytic reforming temperature, on the yields of liquid, carbon residue and gas, and the quantity of gasoline, diesel and heavy oil generated by pyrolysis of PP and LDPE were studied. Facing the fact that the catalyst used in the pyrolysis of waste plastic was costly and few, a light spherical porous biofiltering material was prepared from fly ash used as principal raw material,soil as adhesive agent and organic foaming agent via bailing and high temperature sintering.更多还原
