Method for reducing impurities in catalysts for the production of terephthalic acid |
| abstract |
A method of reducing impurities in a catalyst for the production of purified terephthalic acid, comprising: forming purified terephthalic acid by hydrogenating crude terephthalic acid using a catalyst in a reactor; The diformic acid is separated from the catalyst, and the catalyst is reactivated by washing with a caustic solution; and washing the catalyst contaminated with impurities with a non-caustic solution at a washing temperature greater than or equal to 50°C. |
