Title: Innovations in Waste Polyester Recycling by Dubin Wang
Introduction
Dubin Wang is an innovative inventor based in Shanghai, China. He has made significant contributions to the field of waste polyester recycling, holding a total of 3 patents. His work focuses on developing methods that enhance the efficiency and effectiveness of recycling processes.
Latest Patents
Wang's latest patents include a method for recycling waste polyester through a modified alcoholysis process. This method aims to recycle waste polyester to prepare dimethyl terephthalate (DMT). The process involves using dewatered and deoxygenated waste polyester as a raw material. In this method, an alcoholysis agent, specifically ethylene glycol, is added to the melted waste polyester for preliminary alcoholysis. This approach ensures that the melted material remains in a homogeneous state during the alcoholysis process, preventing it from solidifying prematurely.
Another notable patent by Wang is a method for recycling waste polyester with continuous alcoholysis and transesterification. This invention utilizes a continuous feeding process, allowing for homogeneous alcoholysis in a melted state. By employing multiple alcoholysis tanks in series, the method stabilizes the quality of the alcoholysis product. The continuous transesterification process further enhances the purity and yield of the recycled product, significantly improving the overall efficiency of waste polyester recycling.
