In April 2007 the CTP-IV type Pd/C catalyst for hydrofining of terephthalic acid （TA） developed by the SINOPEC Shanghai Petrochemical Research Institute had been applied in the 320 kt/a PTA unit at the SINOPEC Tianjin Branch Company. Currently this unit operates smoothly at full load and haspassed tests during processing of the stuffs returned from the oxidation section. The PTA quality is stable to comply with the premium grade quality,
