An experimental research project is presented in this article which addresses some key technical issues in the operating process of converting waste plastics into fuels. In particular, these issues have been existing in the manufacture of fuel oils and chemicals from cracking the waste plastics. This study investigated the catalytic cracking action of a self-made catalyst, YNN ( for the polyene plastics), and the reforming action of a self-made molecular sieve catalyst, HC-1 ( for the plastics cracking production), by using an improved fluidized bed as the reactor. The project examined various impacts of several factors such as the reaction temperature and catalyst dosage on reaction process and production. The optimal reaction conditions were identified. Based on these conditions, bench-scale experiment was carried out by using mixed waste plastics. The experiment's product of liquid fuels could meet national standards for auto fuels.
