| titleOfInvention | P-phthalic acid Hydrobon catalyst and preparation method thereof |
| abstract | The present invention relates to for hydrofining crude terephthalic acid catalyst and preparation method thereof, palladium is easy to run off in use mainly to solve palladium carbon catalyst present in prior art, causes the problem that catalyst activity is low.The present invention is by adopting with activated carbon as carrier, the weight/mass percentage composition of palladium is 0.20～1.0%, wherein 70～85% palladium is distributed in 0.2～20 μm of top layer, the top layer of 0～0.20 μm of carrier is distributed in less than 10%, remaining is distributed in the technical scheme of 20～180 μm of internal layer, the problem is preferably solved, be can be used in the commercial production of hydrofining crude terephthalic acid. |
