VERFAHREN ZUR ABTRENNUNG KATALYSATORFREIER ARBEITSLÖSUNG AUS DEM HYDRIERKREISLAUF DES ANTHRACHINONVERFAHRENS ZUR HERSTELLUNG VON WASSERSTOFFPEROXID |
摘要 |
<p>A method is shown for the separation of catalyst-free working solution from working solution, containing noble-metal black, especially palladium black as catalyst, of the hydrogenation cycle of the so-called anthraquinone method for the production of hydrogen peroxide by filtration of the catalyst-containing working solution using filter candles. The filter candles are formed of an open-pore support body based on a carbon material or metallic or ceramic material with an average pore width in a range of 5 to 100 mu m and of a single-layer or multi-layer membrane of ceramic material with an average pore width in a range of at least about 1 up to 10 mu m located on the outside surface of the support body.</p> |
