Process for reducing the carbon content of aqueous hydrogen peroxide solutions |
摘要 |
Aqueous hydrogen peroxide solutions contain variable amounts of carbon compounds following their production by the so-called anthraquinone process. Various methods are known for separating out carbon compounds, including those using organic ion exchangers or macro-porous organic adsorber resins. Described is a process using a solid adsorption agent, which can be regenerated without causing any problems, whereby the carbon content is reduced. The solid adsorption agent is a zeolite from the set of dealuminised H-Y-zeolites with a (SiO2/Al2O3) ratio equal to or greater than 20 or H-mordenites with a (SiO2/A12O3) ratio of at least 20.
