Advances in the slurry reactor technology of the anthraquinone process for H2O2 production

This paper overviews the development of the anthraquinone auto-oxidation （AO） process for the pro- duction of hydrogen peroxide in China and abroad. The characteristics and differences between the fixed-bed and fiuidized-bed reactors for the AO process are presented. The detailed comparison indicates that the production of hydrogen peroxide with the fluidized-bed reactor has many advantages, such as lower operation cost and catalyst consumption, less anthraquinone degradation, higher catalyst utilization efficiency, and higher hydrogenation efficiency. The key characters of the production technology of hydrogen peroxide based on the fluidized-bed reactor developed by the Research Institute of Petroleum Proces- sing, Sinopec are also disclosed. It is apparent that substituting the fluidized-bed reactor for the fixed-bed reactor is a major direction of breakthrough for the production technology of hydrogen peroxide in China.
