项目摘要

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. ***

9504027该奖项为日本国家资源与环境研究所(National Institute of Resources and Environment，NIRE)的万智平博士提供为期18个月的科学技术机构奖学金。他将与NIRE碳氢化合物研究实验室的Yoshiki Sato博士、Tohru Kamo博士和S.Futamura博士合作。犹他大学化学和燃料工程系的David Bodly教授也将参与该项目。这项研究旨在通过选择性溶剂溶解和低严重性条件下的解聚来改进从混合废塑料中回收聚合物和单体的方法。希尔德布兰德的正规溶液理论将被用来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造成转化和处置问题。焚烧和热解等工艺会造成潜在的空气污染问题，并降低塑料的能量回收率。相结合的液相工艺有可能从塑料中回收高质量的材料。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。***
