对苯二甲酸加氢精制催化剂的研究进展

详述了对苯二甲酸加氢精制工艺用钯/活性炭(Pd/C)催化剂、非碳载体的Pd催化剂和多活性中心催化剂的研究进展;指出我国催化剂研究在抗磨损、抗硫性能、钯晶粒易长大等方面与国外的差距较大,今后应研发以二氧化钛、纳米碳等为新型载体制备的催化剂,进一步开发Pd/C催化剂以实现精对苯二甲酸工业化生产。

Research progress in catalysts for terephthalic acid hydrofining process

The research progress in palladium/activated carbon(Pd/C) catalyst,non-carbon supported Pd catalyst and multiple-active-site catalyst for terephthalic acid hydrofinig process was described in details.A distinct gap existed between China and the overseas in the catalyst research on antiwear ability,sulfur resistance and palladium grain growth.The commercial production of purified terephthalic acid should be realized based on the development of Pd/C catalyst and the catalysts using titanium dioxide or nano-carbon as support should be developed.
