Process for the suspension hydrogenation of an anthraquinone compound in a special reactor for the production of hydrogen peroxide

摘要

The invention relates to a method for suspension hydrogenation of an anthraquinone compound of a mixture comprised of two or more anthraquinone compounds in a reactor containing the working solution and the one additional gas phase which contains hydrogen. At least one catalyst is suspended in said working solution. The working solution and the gas phase are at least partially fed into the reactor through a device with openings or channels whose hydraulic diameter is between 0.5 and 20 mm, preferably between 1 and 10 mm, and more preferably between 1 and 3 mm.
