초록 ▼

The invention relates to a process in the continuous catalytic hydrogenation step during production of hydrogen peroxide according to the anthraquinone process by alternate reduction and oxidation of a working soloution of alkylated anthraquinones, said working solution being supplied at the upper end of the hydrogenation reactor and uniformly distributed across the surface of the monolithic catalyst bed, while simultaneously introducing hydrogen gas or hydrogen gas-containing gas, the flow of said working solution through the catalyst bed being adjusted such that the liquid flow is lower than the falling rate of the liquid through the bed, whereby gas bubbles are formed which have a diameter close to the diameter of the catalyst channels, and whereby such gas plugs and corresponding liquid plugs alternately and automatically flow downwardly through said channels and a so-called plug flow is obtained.

대표청구항 ▼

A process for the production of hydrogen peroxide according to the anthraquinone process by alternate reduction and oxidation of a working solution of alkylated anthraquinones, the hydrogenation of said working solution being conducted continuously with hydrogen gas or hydrogen gas-containing gas in a vertical monolithic fixed bed reactor at a temperature below 100°C. and a pressure below 1.5 MPa, wherein said working solution is supplied at the upper end of the reactor and uniformly distributed across the surface of the catalyst bed, while simultaneously introducing hydrogen gas or hydrogen gas-containing gas to the upper end of the reactor, the flow of said working solution through the catalyst bed being adjusted such that the liquid flow is lower than the falling rate of the liquid through the bed, whereby gas plugs are formed which have a diameter close to the diameter of the catalyst channels, and whereby said gas plugs and corresponding liquid plugs alternately and automatically flow downwardly through said channels and a plug flow is obtained.
