| titleOfInvention | Method for recovering metal catalyst components from terephthalic acid spent catalyst |
| abstract | The present invention discloses a process of recovering and recycling a metal catalyst component such as cobalt used in the production process of terephthalic acid. According to the present invention, the waste catalyst generated during the preparation of terephthalic acid is reacted with hydrogen bromide to replace bromine with cobalt and / or manganese, which are the main components of the waste catalyst, and then the above metal catalyst component is recovered by reduction to recover terephthalic acid. It was allowed to be recycled into the manufacturing process. According to the present invention, it is possible to recycle expensive metal catalyst components, as well as recover these components through treatment facilities and processes, which are much more economical than in the past, and waste water does not occur in the treatment process, thereby making it an environmentally-friendly process. Can be achieved.n n n n Terephthalic Acid (TPA), Waste Catalyst, Cobalt, Manganese |
