Hydrogen peroxide is a green chemical product, and its production and usage have almost no pollution, so it is called "clean" chemical product, and its prospect is very promising. Initially, hydrogen peroxide was only used in the pharmaceutical and military industries, and later was gradually applied to chemical synthesis, textile, paper, environmental protection, food, and agriculture, as well as paint, enameled wire, coating, oven, and other industries of organic waste gas VOC purification treatment. In 2000, Shaanxi Kaida began to study palladium catalyst for hydrogen peroxide production by anthraquinone method and its preparation method, and solved relevant problems and technical defects in the technology, including the balance problem of catalyst activity and sample selection, low strength of catalyst carrier, tendency to depowder and break, catalyst service life and regeneration cycle. The promoted palladium catalyst for the production of hydrogen peroxide by anthraquinone method has a very balanced surface area, pore volume and pore diameter distribution, and ensures that the overall particle compression strength of the catalyst is greatly improved, the wear value is greatly reduced, the catalyst is not easy to be depulverized and broken. Therefore, the service life and regeneration cycle of the catalyst are greatly extended.
