Zusammenfassung: | Catalysts, which contain more than 50 % by weight of silicon bound to oxygen and, if appropriate, one or more of the elements, present in a form bound to oxygen or in ionic form, from main groups I to IV of the periodic table, of the elements from subgroups III to VI of the periodic table and/or of the elements phosphorus, arsenic, antimony and/or zinc, are regenerated in the range from 300 to 450 DEG C with a gas mixture which contains molecular oxygen and steam. |
