Peroxide & Catalyst

Hydrogen peroxide is an important chemical product with functions including bleaching, oxidation, disinfection and sterilization. It is widely used in textile, paper making, chemicals, electronics, light industry and sewage treatment without generating any by-products and requiring special treatments. Particularly, its utilization in the environmental protection industry is also becoming increasingly wider.

The LRICI is the first to produce the hydrogen peroxide by the anthraquinone method in China, and enjoys a high reputation both home and abroad. As one of the most influential technologies in LRICI, it has a long history of more than 40 years from research and development to large-scale industrialization. It was granted the National Science Conference Award in 1978, and won the second prize of the National Science and Technology Progress Award twice respectively in 1985 and 1995. The LRICI is also the first to launch the anthraquinone technique that focuses on palladium catalyst and fixed bed hydrogenation. More than 50 sets of equipment have been built in China using this technology in the past 20 years, and the total production capacity has reached more than 4mt/yr (calculated on 27.5 percent concentration). Their products had been exported to Indonesia twice in 1992 and 1996, and negotiations on technology trading with a number of foreign manufacturers are also being held. Moreover, the LRICI also built a 100,000t/yr (27.5 percent total concentration) hydrogen peroxide production plant using its own funds in the Jili Science and Technology Park, in order to promote and demonstrate technological advances and meet the techniques demands in China. Its Annual sales have reached 100 million yuan.

The palladium catalyst produced by LRICI is specially used in the anthraquinone-method hydrogen peroxide production. The facility’s capacity has exceeded 200t/yr, capturing at least 70 percent of China’s market and ranking first in China after the expansion.
