Primary research on the reason of sulfur poisoning of Pd/C catalyst for hydrogenation purification of terephthalic acid;

Internal diffusion and effectiveness factors of Pd/C catalyst for purification of terephthalic acid;

Deactivated Pd/C catalyst of hydrogenation for purification terephthalic acid were studied by EDS(energy dispersive spectroscopy).

The application of palladium-carbon catalyst was intr oduced.

Heat treatment is one of the important catalyst treating processes which significantly affect the catalytic activity of Pd/C catalyst.

Study on a analysis method of spent palladium-carbon catalyst;

The Pd/BC catalyst was prepared through improving the loading process and modifying the bamboo charcoal.

The analysis of key point in the production of hydrogen peroxide with Pd catalyst;

The latest progress of support modification, new supports(including macromolecular support and alumina support with nano-fiber shape), cocatalysts and new preparation technology of the catalysts in the research on the novel Pd catalysts for anthraquinone hydrogenation in recent years is reviewed.

Through the experiment and comparison of regenerating methods using steam,aromatic hydrocarbon and oxidizing solution for Pd catalyst used in the hydrogen peroxide production by anthraquinone process,recommends Pd catalyst regenerating method using oxidizing solution could being applied in the industrial hydrogen peroxide production.
