Japan STA Program: Liquid-Phase Cracking of Waste Plastics

本奖项支持日本国家资源与环境研究所（NIRE）万济鹏博士获得为期18个月的日本科学技术机构奖学金。他将与博士合作。NIRE碳氢化合物研究实验室的Yoshiki Sato， Tohru Kamo和S. Futamura。美国犹他大学化学与燃料工程系教授David Bodily也将参与该项目。该研究旨在通过选择性溶剂溶解和低严重条件下的解聚，改进从混合废塑料中回收聚合物和单体的方法。希尔德布兰德规则溶液理论将用于选择溶解废塑料混合物的溶剂。这些混合物很难通过物理过程分离，而且聚氯乙烯等塑料的污染会产生转化和处理问题。焚烧和热解等过程会造成潜在的空气污染问题，并且塑料的能量回收率很低。联合液相工艺有潜力从塑料中回收高产量的高质量材料。回收产物的化学表征将有助于确定反应产物的组成，帮助选择最佳反应条件，为了解反应机理提供信息，并验证所提出的回收方案的有效性。* * *

9504027 Bodily This award supports an 18-month Science and Technology agency of Japan Fellowship for Dr. Jyi-Perng Wann at the National Institute of Resources and Environment (NIRE). He will collaborate with Drs. Yoshiki Sato, Tohru Kamo, and S. Futamura of the Hydrocarbon Research Laboratory of NIRE. Professor David Bodily of the Chemical and Fuels Engineering Department, University of Utah will also participate in the project. The research is aimed at improvements in the recovery of polymers and monomers from mixed waste plastics by selective solvent dissolution and depolymerization at low-severity conditions. Hilderbrand's regular solution theory will be used to select solvents for the dissolution of waste plastic mixtures. The mixtures are difficult to separate by physical processes, and contamination by plastics such as polyvinyl chloride creates conversion and disposal problems. Processes such as incineration and pyrolysis cause potential air pollution problems and low recovery of the energy contents of the plastics. The combined liquid-phase process has the potential to recover high yields of high-quality materials from plastics. Chemical characterization of the recovered products will provide for determination of the composition of reaction products, aid in the selection optimal reaction conditions, provide information for the understanding of reaction mechanism, and verify the effectiveness of the propose recovery scheme. ***
