摘要
论述了我国PTA行业废渣产生情况和PTA废渣的性质。重点总结了从PTA废渣中回收有机羧酸和催化剂的专利技术,同时对PTA废渣的综合利用的现状和技术做了回顾,认为利用PTA废渣生产增塑剂、不饱和树脂、聚酯漆、活性炭等能变废为宝,具有良好的经济效益和环境效益。
The production and property of PTA waste residue was discussed. Some patents of the separation and utilization of organic carboxylic acid was reviewed,as well as the reuse of this waste. Using the PTA waste to produce plasticizer, unsaturated polyester, polyester paint, active carbon and so on, have the good economic efficiency and the environment benefit.
